factor2

Returns the factors (not only the prime factors) of positive integer k, including k itself.

Description

%A = FACTOR2(K)
%Returns the factors (not only the prime factors) of k, including k itself.
%This complements the usage of TMW's factor function, which returns only
%prime factors.
%E.g., >> a=factor(1365), b=factor2(1365)
% ANS: a = 3 5 7 13
% b = 1 3 5 7 13 15 21 35 39 65 91 105 195 273 455 1365

thank you.
I wonder why such a basic function is not available as a builtin MATLAB function. Even though it includes more complex function to deal with
LU, or triangular, factorization
Cholesky factorization
QR, or orthogonal, factorization
Incomplete factorizations
etc.

Thanks a lot, it was very helpfull indeed.
