It is also known as Multidimensional array. Matrix multiplication is another important program that makes use of the two-dimensional arrays to multiply the cluster of values in the form of matrices and with the rules of matrices of mathematics. A b c d e a b c e f a b c d f.

For example a matrix with only zero values is the zero matrix. As a result of multiplication you will get a new matrix that has the same quantity of rows as the 1st one has and the same quantity of columns as the 2nd one. A matrix is a rectangular array of numbers that is arranged in the form of rows and columns.

For j 0. For example if you multiply a matrix of n x k by k x m size youll get a new one of n x m dimension. How to multiply 2 dimensional arrays.

We can add subtract multiply and divide 2 matrices. You can multiply two matrices if and only if the number of columns in the first matrix equals the number of rows in the second matrix. An example of a matrix is as follows.
