*Square of Matrix Calculator* is an online tool programmed to calculate the square of the matrix A. It is also called as raising matrix to a power calculator which increases a matrix to a power greater than one involves multiplying a matrix by itself a specific number of times for example **A**^{2} = A . A. The matrix may be squared or even raised to an integer power. This square of matrix calculator is designed to calculate the squared value of both 2x2 and 3x3 matrix. User can select either 2x2 matrix or 3x3 matrix for which the squared matrix to be calculated. In many areas such as electronic circuits, optics, quantum mechanics, computer graphics, probability and statistics etc, matrix is used to study. When it comes to calculate 2x2 and 3x3 squared matrix, this online calculator is an essential tool to make your calculations easy
