I have 2 computers, both with windows 7 and both with the 7.10.0 version of MATLAB, both have identical MATLAB programs I created.
I am using the "eval" function in MATLAB and evaluating a address of something like (both computers):
eval([cd C:\Users\Documents\Images\Scan1]);
One computer this works, but the on the other computer it does not work. The one computer that does not works says,
"Error using ==> cd
Too many input arguments."
The one that works does not have this issue at all and works fine, exactly as I intended. I'm really at a loss to enplane or fix why one works and the other does not when they are nearly identical operating systems, MATLAB versions and MATLAB programs. Please help! Thanks, Chris

@Chris: Please search in this forum for "eval". You will find hundreds of suggestions to avoid this function, because it causes more problems than it solves.

Are there spaces in any of the directory names in the path you're cd-ing to? What happens when you just use cd without eval? In fact, why use eval at all? Why not just do
cd(mypath)

On the computer where it does not work, do this:
which cd
See if someone has saved a script named cd that is masking the built-in function. And why are you using EVAL for this purpose anyway?? The command will work without putting it inside EVAL...
cd C:\Users
is the same as:
eval('cd C:\Users')
