Hi my girlfreind has this question, unfortuntly I could not
answer her..please any one can answer
I have a signal transfer function vector H=[H1 H2 H3 . . .
Hm]

I have two data: both data have same x-axis data but
different y-values. I'd like to use double y-axis
(plotyy), AND draw lslines for each data.  
[AX, H1, H2]=plotyy(x, y1, x, y2);

I have a gui created using guide. I would like this gui to
launch in the upper left corner of the screen.
I tried using 'movegui', but I can only get it to work after

When I try to retrieve the data using xlsread, it only return portion of the data.
I have 10050x5 arrays of data. It only returns 472x5 data.

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

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 having some problems to change the parameters of some

Pulse width etc...).
I want to do it using only command prompts i.e. not having

Hi. There are two guide-created Matlab programs A and B. They have

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
