% 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.
