 *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 <math>A_{i,j}</math>,where i=j.
