MATRIXDIAGONALPRODUCT (a)

This function shows the product value of the main diagonal values.
In $MATRIXDIAGONALPRODUCT(a)$ , $a$ 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 of a matrix A is defined by A is the collection of entries $a_{ij}$ ,where i=j.
So diagonal entries are $a_{11},a_{22},a_{33}$ and so on.
Here it is calculating the product of the main diagonal values.
So it is calculating $a_{11}*a_{22}*a_{33}$ and so on.
