Matrix Multiplication Write a program to multiply two compatible matrices. Matrix multiplication can only be performed if the number of columns in the 13 matrix is equal to the number of rows in the 2nd matrix. For instance, if a matrix A is an nximatrix, and matrix B is an l X m matrix, then the product C AxBis an n x m matrix whose elements are calculated according to this equation: aik bkj 1.0 4.0 1.0 15.01 13.0 -1.01 then C Ax B For example, if A 1.0 2.0 [2.0 -3.0 L5.0 -2.0 The program will read the data from a disk file whose first line contains the sizes of the two matrices as 4 integers, which respectively are the number of rows and columns of the 1st matrix, and the number of rows and columns of the 2nd one. The next lines contain the matrices values of their elements in the same order. Each line contains a row of the respective matrix. After populating the operand matrices, invoke the matrix multiplying function by means of an expression, such as c matrixMult(matrixA, MatrixB)
