I'm teaching a collage course (Digital image processing) and I face a problem in the lab software.
Some functions couldn't be used and a message showed in the screen said("undefined function"). I face the same problem with more than one function whiten the image processing toolbox.
You can see what I mean in this picture in the green rectangles:
please help me to solve this problem because i need it in the class I teach!
How can I define these functions in the software.
Thank you. Nora

Nora, you possibly have not installed/licensed the corresponding toolbox(es). What do you get when you execute in the MATLAB command window
which maketform
It should be something like
C:\Program Files\MATLAB\R2013b\toolbox\images\images\maketform.m
Alternatively you could use
to get a list of all installed toolboxes, and
license('test','Image_Toolbox') % returns 1 if toolbox is installed
to see if a particular toolbox is licensed.

When you type ver, if you have the Image Processing Toolbox, you should see something like this:
MATLAB Version 8.2 (R2013b)
Image Acquisition Toolbox Version 4.6 (R2013b)
Image Processing Toolbox Version 8.3 (R2013b)
MATLAB Compiler Version 5.0 (R2013b)
Signal Processing Toolbox Version 6.20 (R2013b)
and so on. Do you see the Image Processing Toolbox listed?
