Need examples for non-linear optimization

In the mathematics - optimization section there is a VI which is..... unconstrained optimization
I am using the downhill simplex option and the input that describes the objective function is "another VI" which I will create.
Are there any examples on how to use this VI since I am not sure how to use the "objective function" input which is a reference to another VI and how to set up the "function data" input either (i.e do you use it specify constants ???? how do you do this ????)

Hi sammy,
You can find more information about this command by right-clicking on the VI and choosing Help. You can then choose the Downhill Simplex option for a detailed description of how to use this VI. The following information is provided in the Help about the "objective VI" you must build:
objective function is a reference to the VI that implements the
function to optimize. Create this VI by starting from the VI template located at
labview\vi.lib\gmath\NumericalOptimization\ucno_objective
function template.vit.
Also, more help information can be viewed here:
Downhill Simplex nD (Not in Base Package)
I didn't find an example program in our Developer Zone, but you might be able to find one by searching the Discussion Forums.
Hope this helps!

I need example for VARIABLES with Customer Exit.

hi every body i need example for Variable for Customer Exit.

Hi,
You can define 'Formula' variables in your customer exit..for example..
you need to calculate no of machine running hours per month, in order to
caculate the machine total utilization time..in this context.. you need to know
how may hours are there in an month by month..
you can define a variable and write the code in the customer exit for deriving the total no. of hours available for that month and get that value into a variable for further calution like deducting the down time and set up time so on..in your
calculated KF..
Hope this helps..
Assign points if useful..
Cheers,
Pattan.

Confidence bounds for non-linear fit

Is it possible to get the confidence bounds for the fitted coeficients when using non-linear fits?

Hello Dahl
Do you mean like Upper Bound and Lower Bound output terminals of NI_Gmath.lvlib::Nonlineat Curve fir intervals.vi?

Constrained non-linear optimization

[fmin, xmin, nIter, kfTolr, kTolr] =
optimize(sFct, x0, eqFct, ineqFct, cType, tolr, maxIter, maxFctcalls,
callback)
I should much appreciate an example of how to use the above
analysis function. Especially the eqFct and ineqFct functions.
How are the constraints used within these functions or are they
used in the calling function?The functions return vectors, but how
are the returned vectors used? Should sFct call any of them?
How are the functions conjoined to determine the La Grange multipliers?
Do I have to add the LG mulitpliers or are they automatically taken care
of?
Thanks!

I think it works that way
SC
function sFct(x)
y=abs(x[1]^2-x[1]-6+x[2]);
return y;
end function;
function ineqFct(x)
->it is of the way hx)<0, if I want x[1]>1, (1-x[1]<0) and x[1]<6 (x[1]-6<0)
and x[2]>3 (3-x[2]<0)
y[1]=1-x[1];
y[2]=x[1]-6;
y[3]=3-x[2];
return y;
end function;
function eqFct(x)
->it is of the way h(x)=0, if I want for instance x[1]=6*x[2]
(x[1]-6*x[2]=0)
y[1]=x[1]-6*x[2];
return y;
end function;
[fmin, xmin, nIter]=optimize(sFct, {v:100,10},eqFct,ineqFct ,);

                     IFunctionTemplate ft=mRepository.getFunctionTemplate("BAPI_COMPANYCODE_GETLIST");
                     myFunction=ft.getFunction();
              }catch (Exception ex)
                     throw new Exception(ex + "Problem retrieving JCO.Function object.");
        if (myFunction == null)
                 System.exit(1);
              myConnection.execute(myFunction);
              }catch (Exception ex)
                     ex.printStackTrace();
                     System.exit(1);
            myConnection.execute(myFunction);
            JCO.Table codes = null;
              codes =myFunction.getTableParameterList().getTable("COMPANYCODE_LIST");
              int size;
             size =codes.getNumRows();
              if (size == 0)
                  System.out.println("No value matches the selection cretaria");
              else
                 for (int i = 0;i<=size; i++)
                        codes.setRow(i);                      System.out.print(codes.getString("COMP_CODE"));                     System.out.println(codes.getString("COMP_NAME"));
       }catch( Exception e)
              e.printStackTrace();
Hope that helps...
Note: in case for the BAPI that inserts or modified data you must call the BAPI_TRANSACTION_COMMIT also for the changes to get reflected in the Database.
Please let me if that helps you.

Need Help for Non Transactional Data

Hi,
I need your help for getting the non-transactional data. I am looking for some solution where I can have employee list with both transaction and non transaction along with the measure in the report.
Thanks in advance.
Phani.

Looks like you either want a procedure with OUT parameters, or to return a record (which you'd need to declare somewhere that your function and calling procedure can both see)

Solving Coefficients for Non-Linear Equation

I have the following equation that I need to solve a, b and c. y = a+bexp(-x/c). Is there a VI that is written to help me?

i don't understand what do you suppose to mean?
you have not a,b and c values and you wanna solve 3 unknown variables with just one equation?
do you think is that possible?
even you had x and y values!
but if you have 4 values and you just want to find another variables value it's so easy
you can easily use a formula node.
i have write a simple program for you to solve this equation and i attached it to this answer.
it's with LabVIEW 5.

Need Examples for asm in sun c compiler

I am having problem with writting inline assembly level language using asm in sun c compiler. I needed few examples like passing variables to inline asm and getting result from the passed varriable. This is somthing like gnuc asm ( Here we have four argument, we can get the result from the argument what we passed)

The asm() syntax is not well supported by our compiler.
The preferred way of doing this is using .il templates to inline assembly
code.

Need URL for non-intel Mac OS X Firefox

Firefox 7 for Intel Mac overwrote a version of Firefox that worked on my non-Intel Mac. No Firefox right now. Can't find usable version of Firefox on Mozilla website.

Found the answer. The correct URL is http://www.mozilla.org/en-US/firefox/all-older.html . The working version is 3.6+
Mac owners take notice---There is no link to the above URL on the Firefox website.
The advice to upgrade to version 4 is bogus.

PPro CS5 Crash Course for Non-Linear Editors

Backstory: I was asked this morning to teach a crash course in Premiere CS5 for the students in the film program at my school in the Introduction to Editing class who have been using FCP. They have to edit several projects using RED footage, and rather than spend a huge amount of time transcoding it to a format which FCP can work with, the prof has just decided to have his students use PPro CS5 (which is also on their editing computers). Since the prof doesn't use PPro, he's asked me to teach the class for him.
I created a very brief crash course powerpoint to assist me in giving them the fundamentals of the program, and supply them with a resource to refer back to as they work on their projects after class is over tomorrow morning. I created this for students who already have done some editing in an NLE, and so don't need to be taught WHAT everything is and HOW to cut footage and put together a timeline. This is just to introduce editors to PPro CS5 who are not already familiar with the PPro workflow.
Anyway, I wondered if some of you gurus would want to take a look at it and give me your feedback on what I've covered well, what I might have missed, and any other thoughts y'all had.
You can view a PDF of the document at www.bryan.edu/pprocs5 The viewer will bring it up embedded in the page at about 40-50%, so you'd be best off to click the download link and open it in Acrobat where you can go full size with it.

Thanks for the input!
I actually taught hem REDCINE-X last week so that they could use it to export their files to an intermediate codec that FCP would understand, and preserve the new colorspace. Unfortunately these computers are so slow that the export process was gonna take nearly a week for all the files they need to work with, so the prof opted to swtich over to PPro midstream since it can handle the raw 4k and supports the new colorspace.
I didn't mention the saving thing... forgot about it; but the conforming issue did come up and we were able to talk about that in class!
The class went okay, I guess... I don't know what it is about students these days, but most of them (like all but one) weren't really paying very good attention and they were just sorta goofing off, talking amongst themselves, etc... made it really frustrating to teach this platform!
Oh well.

Why is the tab functionality not working in Responsive layout? I need accessibility for non-mouse users.

I have generated Responsive HTML5 output. The tab key does not do anything. I want users to be able to tab through the topics and expand or collapse the drop-down hotspots. Tab appears to do nothing. If I generate the same content in WebHelp output users can tab between topics and expand/collapse drop-down hotspots. Is there some sort of setting I have to select to get it to work in Responsive HTML5?

Thanks Phil Flowers !
Good tip !
I' ll be ****.....it actually works too !
This solves the issue of repetatively unplugging and plug back in the wired USB keyboard to the TB display.
Now...if only the Apple support team would acknowledge the problem in the iMac community at large and step up with a hardware / software fix!
Love the TB display......but really...............a non funtioning USB keybord ( apple product ) ???
Maybe they missed the Computer Design & Engineering class that day.....or medicinal marijauna in the valley ?
The support from Apple on this issue reminds me of the 70's video game system ATARI.......The video game PONG comes to mind ....blip....blip....blip.....back and forth with the ball....... And yet we were entertained & amused at the time !
Oh well......they got my dollars too ! Just another unit sold !

Need example for using query string parameters in Web Dynpro

Hello,
Is it possible to transfer a Web DynPro application parameters at the query string (URL)?
Can someone please show me an example of how to pass it and how to retreive it using code inside an application?
Thank you in advance

Hi,
when launching WD apps in the Portal you have to define a WD iView in the Portal. This can be started using the NavigationTarget parameter.
Parameters (ie. Business Parameters) that should be passed to the WebDynpro application can be defined in the iView itself - the iView attribute is called "Application Parameters". Here you can also define variable expressions like "emailaddr=<User.email>" so that the value of the email address is evaluated on runtime.
This way you don't have to care about URL encodings at all
The following user expressions can be used:
<User.displayname>
<User.uniquename>
<User.firstname>
<User.lastname>
<User.salutation>
<User.jobtitle>
<User.department>
<User.email>
<User.telephone>
<User.mobile>
<User.fax>
<User.streetaddress>
<User.city>
<User.zip>
<User.country>
<User.state>
<User.timezone>
