defaults.m

Syntax:
DEFAULTS('Variable',Value)

Problem:
Usually in a function call:
out = function(Var1, Var2)

if (~exist('Var1','var')
Var1 = 1234;
end
if (~exist('Var2','var')
Var2 = 3456;
end

This gets tedious after a while.

Solution using DEFAULTS
out = function(Var1, Var2)
defaults('Var1',1234,'Var2',3456);
