Problem Solution:

Given a matrix, we have to find the normal of a matrix using C program.

Normal of a matrix is the value which is equivalent to the square root of sum of squares of matrix elements.

Program:

The source code to find the normal of Matrix is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully.

```// C program to find the normal of Matrix

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

int main()
{
int Matrix[3][3] = {
{ 9, 8, 7 },
{ 5, 4, 6 },
{ 1, 2, 3 }
};

int i, j, normal = 0;

printf("Matrix:\n");
for (i = 0; i < 3; ++i) {
for (j = 0; j < 3; ++j) {
printf(" %d", Matrix[i][j]);

normal = normal + (Matrix[i][j] * Matrix[i][j]);
;
}
printf("\n");
}

printf("Normal of matrix is: %f\n", sqrt(normal));

return 0;
}
```

Output:

```Matrix:
9 8 7
5 4 6
1 2 3
Normal of matrix is: 16.881943
```

Explanation:

Here, we created a 3X3 matrix matrix using the 2D array. Then we find the normal of the matrix. After that, we printed the Matrix and normal of the matrix on the console screen.
