HISTNORM Histogram normalized
[...] = HISTNORM(...) works like HIST, but the frequency is normalized
so that area sum is 1.
Bonus usage!
[...] = HISTNORM(..., plot ) plots and returns the output arguments.
Be sure plot is the last argument.
Example:
data = randn (10000, 1)
[xo,no] = histnorm(data, 101, plot )
hold on
plot (no, normpdf(no), r )
hold off
