creating built-in variables and extracting formulas from anonymous functions

[Eric S. Carlson]

Hello All,

Two questions:

1. Is there some way to define and initialize a built-in variable
dynamically at startup? Or is there another type of variable I can use that
does not get erased with the clear command?

2. Is there some way to extract the formula of an anonymous function as a
string? (Example - f= @(x) x.^2; f %outputs ans=@(x) x.^2 -- a=sprintf('%s',
f) ->gives an error )

Thanks,
Eric Carlson
