interfacing VB and matlab...need advice

[PATRICK LU]

Hi,

is there a way to get VB progs to call matlab routines? Right now, I'm
using VB as the gui for a spectrogram analyzer and matlab for the
intensive calculations, but both are working independently. Any advice on
how to integrate the two would be appreciated.

thanks,

Pat Lu

Pat,
Isn't MATLAB OLE enabled? Take a look at the beast in the Obj Browser and
see what
bright flashes illuminate the grey matter ;-) If not OLE enabled can you
ferret out its menu
commands with Spy++ and send WM_COMMANDS where necessary or
Sendkeys/Pushkeys
where desperate???

there's some documentation of this in the books. i've done it in matlab 5.2
and 5.3. i think the book is called "application programming guide" or
something like that.

from memory:

Dim Matlab as Object

Set Matlab = CreateObject("Matlab.Application")

'some of my code
Call Matlab.PutFullMatrix("outwavs", "base", outwavs, junkspec)
result = Matlab.Execute("[outspecs]=resamp(inwavs, inspecs, outwavs);")
Call Matlab.GetFullMatrix("outspecs", "base", outspecs, junkspec)

'clean up
Matlab.Quit
Set Matlab = Nothing

note that starting matlab will likely take longer than executing the code.
our solution has been to use matcom (www.mathtools.com) to translate matlab
to c++. works well, although matcom's recently gotten rather expensive.

Hi,

Can anyone tell me how to execute a matlab file directly of the web?
whenever i make a hperlink i get the matlab editor window opened
instead.
