If you do not have MATLAB Coder installed (as indicated by ver) then the commands ccoder and coder will not work and should not be installed. That ccoder is recognized at all is probably a bug. However, the directory toolbox/coder may be installed and contains shared components used by other products.

I apologize if I didn't understand this properly but think the command is just 'coder' and not 'ccoder'. Upon typing coder in the command window, a GUI will pop upfor the new project file and then you continue as you normally would.

after typing just coder it says 'undefined command or variable'

[Kaustubha Govind]

Ajinkya: What version of MATLAB are you using? Also, when you execute the command ver at the MATLAB prompt, is MATLAB Coder listed amongst the installed products?

[Ajinkya Talele]

I'm using MATLAB 2012b. no it does not show matlab coder when i type ver. But it shoes the coder folder where it is installed..

Hi Anjinkya,

I faced similar problems for getting Matlab coder to work.

Can you try the following commands:

$ rehash toolboxcache

$ restore defaultpath

$ savepath pathdef.m

And see if matlab coder works for you.

ok i'll try it thnx a lot
