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

17 views (last 30 days)
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

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.

Parallel Computing Toolbox Version 4.3 (R2010a)
So it is installed. Please tell me if i were doing some other mistake?
