Due date: Thu 3/2
10 points

1. Write a program that reads two matrices and determines their product matrix.

For example:

           1  2  3                            1  2  3  4  5
M1 =                  and      M2 =  2  5  3  1  4
           3  2  1                            5  4  3  2  1

then

          20  24  18  12  16
P = 
          12  20  18  16  24

Requirements:

• Implement the following functions:
  • float *allocate(int rows, int cols);
    void readm(float *matrix, int rows, int cols);
    void writem(float *matrix, int rows, int cols);
    void mulmatrix(float *matrix1, int rows1, int cols1, float *matrix2, int cols2, float *product);
• Input the row size and column size for matrix M1 and M2
• Input the matrix
• Validate the product matrix dimension
• Validate the memory allocation

Hint:

void mulmatrix(float *matrix1, int rows1, int cols1, float *matrix2, int cols2, float *product)
{int i, j, k;
      for (i = 0; ________________ )
             for(j=0;________________ )
            { 
                 for(k = 0, *product = 0;________________________)
/* p[i,j] += m1[i,k] * m2[k j]*/
            *product += matrix1[_____________] * matrix2[_________________];
     product++;
}
}
