Error:Undefined function or method 'gpuArray' for input arguments of type 'uint8'

When i used gpuArray while coding,

 originalI = imread('cameraman.tif');
 se = strel('disk',5);
 erodedI = imerode(gpuArray(originalI),se);
 figure, imshow(originalI), figure, imshow(erodedI)

It resulted in the following error

   Undefined function or method 'gpuArray' for input arguments of type 'uint8'

What is the reason for this? Please tell me.

I am using MATLAB 2010a.

Thanks in advance

Not sure if the function existed in R2010a. What do you get when you run "which gpuArray"?

[Sean de Wolski]

gpuArray and GPU support was released in R2010b. If your company/university's SMS subscription is up to date, you can download the newest release at no additional cost.

gpuArray is a function of the 'Parallel Computing Toolbox'. Without this toolbox, the function can not be called. The command 'ver' lists all installed toolboxes.

I have Parallel Computing Toolbox. As you told when entering the command ver i got

 Parallel Computing Toolbox                     Version 4.3        (R2010a)

So it is installed. Please tell me if i were doing some other mistake?
