MATRIXIDENTITY(n)

• $n$ is the order of the matrix.

Description

• This function shows the identity matrix of a given matrix.
• In $IM(n)$,$n$ is the Order of identity matrix.
• Identity matrix is also called Unit matrix.
• Identity matrix of size n is the nxn square matrix with ones on the main diagonal and zeros on the other entries.
• Identity matrix is denoted by $I_{n}$.
