Question
Matrix Multiplication!
Objective:
Write a program that can create two matrices and then it multiplies them!
The user first inputs the size length and width
Next the user populates that matrix with data
The user then inputs the size length and width of the next matrix
Once again they populate it
Next the program must check to see if the dimensions match
A n-by-m matrix can only be multiplied by a m-by-l matrix where n, m, and l correspond to the sizes of the matrices.
If they do match correctly then create a new matrix and put the newly multiplied info inside of it.
Multiply the individual numbers of the first matrix’s columns by the individual number of the other matrix’s row and add those together.
The matrix size when multiplying a n-by-m by a m-by-l will result in a n-by-l matrix
