I need help in this program about matrix in C

Write three matrix math functions: add Matrix which will add two matrices such that result = matrix1 + matrix2 sub Matrix which will subtract two matrices such that result = matrix1 - matrix2 molt Matrix which will multiply two matrices such that result = matrix1 x matrix2 Given the following source matrices: The function add Matrix produces the following matrix as its result: The function subMatrix produces the following matrix as its result: The function multMatrix produces the following matrix as its result: M1 times M2 = [75.84 108.05 89.24 93.31 124.51 141.59 133.13 183.26 179.25] The prototypes for the three functions must be: void addMatrix(const double matrixl[][3], const double matrix2[][31, double result[][3], lnt rows); void subMatrix(const double matrixl[][3], const double matrlx2[][3], double result[][3], lnt rows); void multMatrix(const double matrixl[3][3], const double matrlx2[3] [3], double result [3] [3]); The addMatrix and subMatrix functions will handle matrices with any number of rows - the last argument (rows) tells the function the number of rows. All matrices that these functions handle will have three columns. The multMatrix function will multiply a 3 times 3 matrix by another 3 times 3 matrix to produce a result matrix that will also be 3 times 3. You will need to write a driver to test your functions. We will test your functions with our driver Our driver will call your functions as specified by the prototypes as given above
