optimization

[gogo1122]

Dear all :

I have a function (eg:f(x,y,z))and I need to find minimum of x,y and z, first I use Downhill simplex nD  (in lv7.1) but the solution isn't good

When I calculate in matlab.I got a correct solution.

I find a tool in lv8.0(mathscript->fminsearch)

Can someone tell me why ?? Is  mathscript's fminsearch equal matlab's fminsearch

If they are the same. can you give me an example how to use fminsearch in mathscript.

The problem has confused me for a long time.

My boss urges me everyday.  I hope you can help me please

Thanks a lot

you would get better response if you posted in the labview forum instead of the breakpoint.

Hello,

You might want to take a look at TOMVIEW for your optimization needs. Possibly you could use SNOPT to solve the problem, or a global solver like glbDirect in the Base Module.
