error with gpuarray transformation

>> A3 = gpuArray(q);
Error using gpuArray
Only full arrays of fundamental numeric types or logical types are
supported for GPU arrays.

i get the following error message. q is a cell array consisting of a matrices with many thousand rows.

my gpu is a cuda card with 4 gigabytes.

thanks

q is not allowed to be a cell array. It must be a matrix or n-dimensional array. And it must be non-sparse.

Is there a solution to this problem?

[Edric Ellis]

No, you cannot put a cell array on the GPU. You can make a cell array containing gpuArrays if you wish, like so:

A = cellfun(@gpuArray, {1, 2, 3}, 'UniformOutput', false)

Not sure whether that's any use to you.

[AA]

so any calculations I do after this will be transformed using gpu rather than cpU?

[AA]

A = cellfun(@gpuArray, a, 'UniformOutput', false)

[Matt J]

All operations on A{i} will be done on the GPU.

[AA]

A = cellfun(@gather, a, 'UniformOutput', false) and this turns it back
