C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the
We also show that, using our diagonal framework, Java native arrays can yield superior computational performance. We present two alternative implementations for matrix-matrix multiplication operation in Java. The results from numerical testing demonstrate the advantage of our proposed methods.Mahmud, ...

ParserNG of course allows matrix multiplication with ease. To multiply 2 matrices in 1 step: Do, MathExpression mulExpr = new MathExpression("M=@(3,3)(3,4,1,2,4,7,9,1,-2);N=@(3,3)(4,1,8,2,1,3,5,1,9); P=matrix_mul(M,N);P;"); System.out.println("soln: "+mulEx...
The column of first matrix should be equal to row of second matrix for multiplication. If this condition is not satisfied then, the size of matrix is again asked using while loop. Then, user is asked to enter two matrix and finally the output of two matrix is calculated and displayed. Si...
