For example: if A = B.transpose(), then a[i][j] = b[j][i]. 
 
-const Matrix add(const Matrix &m) const: adds the corresponding elements of the two matrices and returns result.
 
For example: if C = A.add(B), then c[i][j] = a[i][j] + b[i][j]. 
 
-const Matrix subtract(const Matrix &m) const: subtracts the elements of the two matrices and returns result.
 
For example: if C = A.subtract(B), then c[i][j] = a[i][j] - b[i][j]. 
 
-const Matrix multiply(const Matrix &m) const: multiplies the elements of the two matrices and returns result.
 
For example: (A and B are 2 X 2 matrices) if C = A.multiply(B) and , then c[0][0] = a[0][0] * b[0][0] + a[0][1] * b[1][0].
