Permute diagonal and antidiagonal
For example [1 2 3;4 5 6;7 8 9] -> [3 2 1;4 5 6;9 8 7]
WITHOUT diag function (and variable name)
"max(...)" is clever!
Arrange Vector in descending order
Calculate the area of a triangle between three points
We love vectorized solutions. Problem 1 : remove the row average.
Negation and new variables
Generalised Hamming Number
Find indices of diagonal elements
