Problem 679. Alias abs to asb

Create an alias of a built-in function name.

Goal is to alias asb with abs for dyslexic typers.

The test suite will be

 %%
 global asb;
 k=-randi(10);
 y=make_alias(1);
 assert( isequal ( abs (k), asb (k) ) )
 % End of test

My solution uses "global asb" inside the make_alias function.

Purpose: Some names may be long and substituted by short names.

My personal nemesis is figrue.

I want an auto-correct option in the editor for a custom wordlist.

My second nemesis: function9x). MATLAB should know I meant function(x)
