I want to use "set_param" in my GUI.But everytime I got some errors.My codes;
--------------------------------
m=str2num(handles.edit2,'String')); %Get value as a number from editbox
set_param('MH1/Signal Generator', 'Amplitude',m);%Change the amplitude
--------------------------------
It didn't work.Then I tried;
set_param('MH1/Signal Generator', 'Amplitude','5');
It has worked.But I want to use a variable to change the amplitude of signal generator.How can I do this?
Thanks.

Not enough information. What SPECIFICALLY do you mean by "It didn't
work" -- did you receive a warning? An error? A different answer from what
you expected?

Assuming that you receive from STR2NUM a value that's a valid Amplitude for
the Signal Generator block, what you posted should do. Since it didn't,
there's really nothing we can do until or unless you post additional
information about what happened. [Post it to the newsgroup, please, rather
than sending it to me directly. I am going to be out of the office for a
few days, and I wouldn't have a chance to look at it before I leave.]

Several block parameter values must be specified as strings. So in your case, you could do the following:

m=str2num(handles.edit2,'String')); %Get value as a number from editbox
set_param('MH1/Signal Generator', 'Amplitude',num2str(m));

Hope that helps.
