sorry i been stuck on this question for past couple hours. it would be great help you if you could explain lil more. thanks, much appreciated

[Walter Roberson]

Did you try playing with the Example on the diag documetnation? Assign an integer value to "m" and then run the line of code and see what it gives. Then start picking apart the parts of the expression to see how the parts fit together.

For a 5x5 matrix, the main diagonal needs to have 5 elements: [2 2 2 2 2].
