Find the minimum value of matrix.
resMin = gpuMin(A)
Can be :
Pointer on the matrix stored in GPU memory.
Pointer on the matrix stored in CPU memory.
resMin is the result of computation in host memory (CPU).
gpuMin
find the minimum value of matrix A.
To find the minimum value of complex matrix, the function performs operation abs(real)+abs(imaginary).
This function use cuBLAS to perform operations only with complex matrix.
