Matrix Multiplication - Applet
This applet helps you explore the definition and process of multiplying matrices.
The elements of the matrix are easy to change. The interface makes it easy to understand the definition of the multiplication process.
1-Set the elements of each matrix (A and B),to some values, using
the scrollbars, highlight a row in matrix A and a column in matrix B
and check that the highlighted element in C is obtained according to the rule
of multiplication of matrices.
2-Set matrix A equal to the identity matrix of order 3 (matrix that consists of 1's on its main diagonal and 0's elsewhere)compare matrices B and C. Explain.
