Good grief!

n.aggel, you had the right idea to begin with, only your syntax needs help. Don't change the definition of the function, but just pass the appropriate pointer.

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
void array_function(int rows, int cols, float after[rows][cols] , float before[rows][cols])
  {
  ...
  }
 
int main()
  {
  int n = 5;
  int m = 6;
 
  int before[n][m];
  int after[n][m];
 
  array_function( 5, 6, before, after );  // this works
  array_function( 5, 6, after, before );  // this works
 
  ...
  }
void array_function(int rows, int cols, float after[rows][cols] , float before[rows][cols])
  {
  ...
  }

int main()
  {
  int n = 5;
  int m = 6;

  int before[n][m];
  int after[n][m];

  array_function( 5, 6, before, after );  // this works
  array_function( 5, 6, after, before );  // this works

  ...
  }

Hope this helps.
