Error using construct_error (line 108) The current directory is c:\program files\matlab\r2012a\bin, which is reserved for MATLAB files. Please change your current directory to a writable directory preferably outside of MATLAB installation area

No!

Unless you post relevant parts of your code so the error has a context.

If you post the code, which causes the error, a meaningful suggestion is possible. Without any details I repeat the suggestion given in the message already:

 Please change your current directory to a writable directory preferably outside of MATLAB installation area

Eitehr use cd or even better create the file name with a full path. Relative file names are prone to errors.
