I got error while executing this solution

a = gpuArray(1:0.5:5);
n1 = numel(k);
n2 = numel(a);
numpl = repmat(k, 1, n2)';
denpl = repmat([ones(n2,1), a.', zeros(n2,1)] ,n1, 1);

You have to mention the error....

[nelson]

Error using set While setting the 'YLim' property of 'Axes': Value must be a 1x2 vector of numeric type in which the second element is larger than the first and may be Inf

Error in plottmpl (line 50) set(a,'box','on','xgrid','on','ygrid','on',...

Error in Untitled22 (line 15) plottmpl(w,w,P);

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

[nelson]

thank u.... But when i am running the same code without GPU m getting the template. But when m converting in GPU m getting the above errors.

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

plottmpl appears to be http://www.codeforge.com/read/216700/PLOTTMPL.M__html

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.
