Factorial

This code gets factorial of a number and for negative numbers returns 1.The recursive implementation of factorial is easy but using lambda keyword of python it becomes a bit tough as we can't use conditional if else in lambda. If a user wants to return a factorial function on the fly using lambda... Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script is similar to fullfact, however instead of number of levels, value of levels are required as inputusage: des_mat = full_fact([-1 1],[100 200 300],[1:4]); arguments: (input) x1,x2, x3- variable levels either in row or column vector. These are not number of levels but the levels itself... Platforms: Matlab
