You are indeed correct as to the coding issue. As to Peter's suggestion, I
would disagree with it for two reasons: 1) Its called a unit step function,
so to have it step more than once seems misleading to me. Possibly the
function he is suggesting should simply be called step or similar.
2) His code is based on the postion inside the vector, not the values
contained within the vector. Maybe that sort of unit step function could
also come under a different name.
I like the way my function is coded for reasons previously listed (and as
Soren has simplified), and that I can simply create a numbered vector as
such:
n=-3:5;
and regardless of the start and end values, the step function will 'step'
when n=0 or any other specified time (that may even be outside the range of
the vector).
x = ustep(n,2) in previous example returns:
x = [0 0 0 0 0 1 1 1 1]
I accept Soren's simplification suggestions, but it will take me a little
while (approx. a week) to change things (as well as this documentation
suggestion) as I am going to have a very busy weekend doing uni work.
