here 's an example of static and dynamic allocation...
(my prev example was only about single dimensional arrays...)

a 2dimensional array of  4450 x 4450
(change the dimension to 1450 x 1450 if  u find the
first size to be too big)

TEST.C
#include <stdio.h>
int main()
{
  double a[4450][4450];

  a[4449][0] = 999;
  printf( "%lf\n", a[4449][0] );
  return 1;
}


TEST2.c
#include <stdio.h>
int main()
{
  double **a;
  int i;

  a = (double**) calloc( 4450, sizeof(double*) );
  for ( i=0; i <1450; i++ )
  {
    a[i] = (double*) calloc( 4450, sizeof(double) );
  }

  a[4449][0]=999;
  printf( "%lf\n", a[4449][0] );
  return 1;
}
