How do I create a symmetric matrix with a linearly decreasing diagonal in MatLab?

I'm trying to create a symmetric n by n matrix where the symmetry line is linearly decreasing from n to 1. For example a 5 by 5 would be: 5 4 3 2 1 4 4 3 2 1 3 3 3 2 1 2 2 2 2 1 1 1 1 1 1 Thanks

Using implicit expansion, the min function will generate a square matrix from the combination of a row and a column vector, so the result can be gained by doing: N = 5; A = min( (N:-1:1).', (N:-1:1) )...

Filling matrix with characters so they form a neat cross, where every lesser diagonal is (char + 1)

The goal is to plot this pattern, where N is in [4,100] range. Main diagonals are always 'a', neighbours of a should be b, neighbours of b should be c and so on. If we have already iterated to z char...

Let's see some of the issues. If the function that shuffles the array is well written, it will change the order of elements in the array, without "loosing" any of them. That means that if t...
