*<math>Number</math> is the order of the matrix.
==Description==
*This function shows the identity matrix of a given order.
*In <math>EYE(Number)</math>,<math>Number</math> is the order of a 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:
<math>I_1=[1]</math>,
<math>I_2 =\begin{bmatrix}
1 & 0 \\
0 & 1
\end{bmatrix}</math>,
<math>I_3= \begin{bmatrix}
1 & 0 & 0 \\
0 & 1 & 0 \\
0 & 0 & 1
\end{bmatrix}</math>......
<math>I_n =\begin{bmatrix}
1 & 0 &0 \cdots & 0 \\
0 & 1 & 0 &\cdots &0 \\
0 & 0 & 1 &\cdots &0 \\
\vdots & \ddots & \vdots \\
