I have a question on filling a lower triangular matrix using numpy. This
is essentially having two loops and the inner loop upper limit is the
outer loop current index. In the inner loop I have a vector being
multiplied by a constant set in the outer loop. For a matrix N*N in size,
the C the code is:
for(i = 0; i < N; ++i){
for(j = 0; j < i; ++j){
Matrix[i*N + j] = V1[i] * V2[j];
}
}
Thanks
Tom
