DIAGONALMATRIX(Order)

• $Order$ is the size or order of the matrix.

Description

• This function shows the Diagonal matrix of a given order.
• In $DIAGONALMATRIX(Order)$, $Order$ is the order of square matrix.
• A diagonal matrix is a square matrix which is of the form $a_{ij}=c_{i}\delta _{ij}$ where $delta_{ij}$ is the Kronecker delta, $c_{i}$ are constants, and i,j=1, 2, ..., n.
• The general diagonal matrix is of the form:

${\begin{bmatrix}c_{1}&0&\cdots &0\\0&c_{2}&\cdots &0\\\vdots &\vdots &\ddots &\vdots \\0&0&\cdots &c_{n}\end{bmatrix}}$ As stated above, the off-diagonal entries are zero. That is, the matrix A = (ai,j) with n columns and n rows is diagonal if
