/*PROGRAM TO IMPLEMENT GAUSS-jordan method.

#include
#define MX 20
main()
{
float a[MX] [MX+1],m,p;
int i,j,k,n;
puts("\n how many equations?:");
scanf("%d",&n);
for(i=0;i<=n-1;i++)
{
printf("Give the coefficients of the equation no%d:\n",i+1);
for(j=0;j<=n;j++)
scanf("%f",&a[i][j]);
}
for(k=0;k<=n-1;k++)
{
for(i=0;i<=n-1;i++)
{
m=a[i][k]/a[k][k];
p=a[k][k];
for(j=k;j<=n;j++)
{
if(i==k)
a[i][j]=a[i][j]/p;
else
a[i][j]=a[i][j]-m*a[k][j];
}
}
}
for(i=0;i<=n-1;i++)
printf("\n X[%2d]=%5.2f",i,a[i][n]);
