Description

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

See also: HIST.

MATLAB release
