Diagonal of a matrix in c
Web4. You need to dynamically allocate your matrix. For instance: int* mat; int dimx,dimy; scanf ("%d", &dimx); scanf ("%d", &dimy); mat = malloc (dimx * dimy * sizeof (int)); This creates a linear array which can hold the matrix. At this point you can decide whether you want to access it column or row first. WebSep 16, 2024 · Definition 7.2.1: Trace of a Matrix.
