Re: Matrix initialization in Library mode


So, once I've allocated my matrix, say

    GEN dell=cgetg(first_size+1,t_MAT);
    for(long j=1; j<=first_size; j++) {
      dell[j]=lgetg(second_size+1,t_COL);

how do I actually fiddle with the elements? Upon trying to

      dell[first_index+1][second_index+1]=stoi(value);

all I receive is a compile error:
homology.c:220: invalid types `long int[int]' for array subscript
