MATRIXDIAGONAL (a)

This function shows the main diagonal values.
In $MATRIXDIAGONAL(a)$ , $a$ is any square matrix.
The main diagonal of a matrix consists of those elements that lie on the diagonal that runs from top left to bottom right.
Main diagonal is also called principal diagonal, primary diagonal, leading diagonal, or major diagonal.
So main diagonal of a matrix A is defined by A is the collection of entries $a_{i,j}$ ,where i=j.
Diagonal entries are $a_{11},a_{22},a_{33}$ and so on.
