The error you have specified has nothing to do with the code you have given..

Okay Okay...you are getting error in this function: plottmpl(w,w,P) it is not a inbuilt function..show us this function.

Use the debugging 'Stop on errors' option from the Breakpoints menu, then you will see instantly what the problem is.

That code was not designed to expect the possibility that the data was on the GPU.
Please see attached for a modified version that gather()'s the data it needs.
Note: execution of this code also requires the following functions from http://www.codeforge.com/article/216700
bndsdef.m freqcp.m qatan4.m qftdefs.m qsubset.m repltest.m
Grabbing the source is a minor nuisance if (like me) you do not have a codeforge account -- you cannot just copy and paste the source.
