Hello.
if someone had a similar problem, I would like to know how to copy one array into another but on such way that values in another matrix represent the index of a first matrix elements?
If you don’t understand what am I talking about look at the picture:
OK, guys, I solved this in C, but know I have the similar problem on CUDA device.
I need to do this:
This is my code. Only thing what is missing is index in first braces.
__global__ void MeanShiftCalc(int *input, int *moment_x_d, int *moment_y_d, int *masa_x_d, int *masa_y_d){
int tx=threadIdx.x;
int ty=threadIdx.y;
for(int i=0;i<a_a;i++){
moment_x_d[]+=(i+1)*input[ty*a_a+i];
masa_x_d[]+=input[ty*a_a+i];
moment_y_d[]+=(i+1)*input[i*a_a+tx];
masa_y_d[]+=input[i*a_a+tx];
}
}
Help!

Help!
Solved it, just have to write ty in misssing position!
