prctile

PURPOSE ^

% For a sample @var{x}, compute the quantiles, @var{y}, corresponding

SYNOPSIS ^

function q = prctile (x, p, dim)

DESCRIPTION ^

% -*- texinfo -*-
% @deftypefn {Function File} {@var{y} =} prctile (@var{x}, @var{p})
% @deftypefnx {Function File} {@var{q} =} prctile (@var{x}, @var{p}, @var{dim})
% For a sample @var{x}, compute the quantiles, @var{y}, corresponding
% to the cumulative probability values, P, in percent.  All non-numeric
% values (NaNs) of X are ignored.
% 
% If @var{x} is a matrix, compute the percentiles for each column and
% return them in a matrix, such that the i-th row of @var{y} contains the 
% @var{p}(i)th percentiles of each column of @var{x}.
% 
% The optional argument @var{dim} determines the dimension along which
% the percentiles are calculated.  If @var{dim} is omitted, and @var{x} is
% a vector or matrix, it defaults to 1 (column wise quantiles).  In the 
% instance that @var{x} is a N-d array, @var{dim} defaults to the first 
% dimension whose size greater than unity.

% @end deftypefn
