18 Dec 2007 Brownian Motion Function to simulate Brownian Motion Author: Abhirup Lahiri x@y.z, Jos

What I like: it pre-allocates the output.

What I do not like:
1) The help is very poor: if I follow it, the function errors when I enter a time vector (e.g., 1:10) and a number of samples (10). Probably t is to be a scalar also, but that is not clear. It has no H1 line, no useful help on its inputs or outputs, no example.

2) It has no error checks on its inputs, checking for common mistakes (like no scalar inputs).
 
3) It is poorly programmed, calculating unused variables, etc, setting the rand state without warning, no internal comments

4) it is very trivial, and can be coded in one line: "w = [0 ; cumsum(sqrt(t/n).*rand(n-1,2))]; "

Finaly, try to make clear why anybody wishes to use of this function.

I think this submission is to be rated 1.5 stars ...
