Problem 24. Function Iterator
Given a handle fh to a function which takes a scalar input and returns a scalar output and an integer n >= 1, return a handle fh2 to a function which applies the given function n times.
Examples:
>> addOne = @(x)x+1; >> addTen = iterate_fcn(addOne, 10); >> addTen(3) ans = 13
>> squarer = @(a) a^2; >> fh2 = iterate_fcn(squarer, 3); >> fh2(3) ans = 6561
% Golden Ratio >> fh = @(y)sqrt(y+1); >> fh2 = iterate_fcn(fh,30); >> fh2(1) ans = 1.6180

Help,help, I can't do it.
usefully skills learned while doing problems.
@Yin Late reply, but: as far as I know, forbidden functions (on Cody in general) are, at least, assignin, builtin, dos, eval, evalc, evalin, inline, path, perl, rehash, str2func, system, and unix.
