I want to initialize a 2D matrix by filling it with random numbers (doubles).
So, for example, this code
#define N 1000
int main(void){
double A[N];
arc4random_buf(A,N*sizeof(double));
return 0;
}
runs and produces a 1D array filled with random numbers as expected.
However, this
#define N 1000
int main(void){
double A[N][N];
arc4random_buf(A,N*N*sizeof(double));
return 0;
}
produces a segmentation fault. I've tried initializing A with zeroes on the previous line, to no avail.
Is the only solution to use a loop here?
