gpuSum

Perform the sum of a matrix.

resSum = gpuSum(A)

A

Can be :

Pointer on the matrix stored in device memory (GPU).

Pointer on the matrix stored in host memory (CPU).

resSum

resSum is the result of computation in host memory (CPU).

resSum = gpuSum(A)

gpuSum perform an addition between all elements of matrix.

A = rand(200,300) + %i * rand(200,300);
dA = gpuSetData(A);

resSum = gpuSum(A)
resSum1 = gpuSum(dA)
resSum2 = sum(A)

dA=gpuFree(dA);
