I am unsure of when to create a subfunction or private function.
When should someone use a private function or subfunction?
Thank you

I'm having some problems to change the parameters of some
blocks e.g. the pulse generator block parameters (Amplitude,
Pulse width etc...).
I want to do it using only command prompts i.e. not having

There is another thread about C.C. going, so rather than
hijack it I will start another.
Can someone show me by example what this is really about?  I
am especially interested in how this relates to code length.

I'm looking for the method to generate a formatted string
the fastest.
Consider this generic case:
input = 1;

I am running a simulation within MATLAB based on time.  In
this simulation I want to be able to speed up and slow down
time.  The code works in this manner:
A while loop is executing upon execution of a pushbutton

Hi. There are two guide-created Matlab programs A and B. They have
their own private callbacks. I would like to define a function in B
and call it from A. Has anyone had any experience with that?

I am attempting to import 2 sets of data from 2 text files
and then putting the data equal to a single variable. The
data in the text files are as follows.

Where i can find  a free download for shapefile???
I need a more precision shapefile of Quebec and Canada...
Thank you!

I'm trying to run a radon transform on a masked image.  The
problem is that the mask on the image throws off the
transform and the border of the mask ends up being the most
significant line.  I tried applying the mask to the image

I'm capturing images with a video device in simulink and
would like to send a signal to my NI-DAQ-card (PCI-6251)
when some change in my images occur. The capturing and
handling of images works fine. But I don't have any

Got a bit of a problem.
I'm trying to read some binary data with fread, and i am receiving them wrong
somehow.
For example:

If I have an unknown z=f(x,y) and I want to "map" it, say by contours
over xmin<x<xmax and ymin<y<ymax. Thus given x,y I can compute z. But
each such computation is fairly expensive. [Perhaps one can pretencd
there is a "cost" of each evaluation and impose a maximum on the number ...

I want to transfer data created in one GUI to another. I am
simulating a matrix in the first GUI, after that I want to
open the other GUI and in that GUI I want to plot the
matrix. I need to know how to open the other GUI from the

Zthjsl(timel)=(Rjs1*(1-exp(-timel/taujs1)))+(Rjs2*(1-exp(-
timel/taujs2)))+(Rjs3*(1-exp(-timel/taujs3)))+(Rjs4*(1-exp(-
timel/taujs4)))+(Rjs5*(1-exp(-timel/taujs5)))+(Rjs6*(1-exp(-
timel/taujs6)));

I have to do operation Bt*inv(A)*B ,I am currently facing problem with the above operation as inv(A) is ill conditioned. Can you suggest some methods to solve the same?
Thanks a lot.
