Matrix Programs

Matrix relates to mathematics that can be defined as a 2-dimensional array in the form of a rectangle which is filled either with numbers or symbols or expressions as its elements. The matrix has a row and column arrangement of its elements.

A matrix with m rows and n columns can be called as m × n matrix. Individual entries in the matrix are called element and can be represented by a^ij which suggests that the element a is present in the ith row and j^th column.
