Implement matmul, subtract, add function.

[Ishwarendra]

• Add function signature for each function inside the Matrix class in matrix.hpp and also implement in matrix.cpp.

• Function specifications:

  • matmul: Multiplies two Matrices. A Matrix and a scalar is not allowed. Also throw appropriate exception if matrix dimension are not compatible for multiplication.
  • add: This function will have two overloads one which will add matrix and scalar and the other one for two matrices. Throw appropriate exceptions if matrix have incompatible dimensions.
  • subtract: Everything same as add function but you should do subtraction instead of addition.

• Don't implement from scratch, use the already implemented functions operator +=, operator -= and operator *=. This way you will not have to worry about throwing appropriate exceptions as the already implemented function will do it for you.

• Don't forget to add comments above each function signature you add in matrix.hpp. Avoid adding comments in matrix.cpp unless very important.
