i do know what a pointer is, and i know what to put for n, a and lda. i am not sure about what to put for the others and Y. I will only be using this on a nxn matrix.

i am trying to call a function that exists outside of my main c file, but i am having some trouble with getting it setup and what to pass it.
this ithe my main file.



#include <stdio.h>...

if i change the declarations to


double matnorm1(double A[][2], int m, int n);

then it works for the 2x2 matrix in main, but i want it to flexible to handle any matrix specified as mxn

im having trouble compiling this,



#include <stdio.h>
#include <math.h>

double matnorm1(double **A, int m, int n)
{
double norm=0.0;
