operations on a 2D array in CUDA kernel for matlab

Question

suppose I have the following serial C:

int add(int* a, int* b, int n)
{
    for(i=0; i

        

Answer 1

I am assuming you are working with n-by-n, row major order array. Try the following :

__global__ void calc(int *A, int *B, int n)
{
    int i= blockIdx.x * blockDim.x + threadIdx.x;
    int j= blockIdx.y * blockDim.y + threadIdx.y;

    if (i
