If @var{x} is a matrix, computes @var{p} for each column of % @var{x}. If @var{p} is a vector, the returned value is a matrix with % one row for each element of @var{p} and one column for each column of % @var{x}. If @var{x} is a vector, then @var{y} is a vector with the % same size as @var{p}. If the argument @var{dim} is given, operate % along this dimesnion rather than the columns of the matrix. % % The first and last values are pegged at 0 percent and 100 percent % respectively, and the rest of the values are uniformly spaced between % them, with linear interpolation between the points. This is % consistent with the definition of quantile given in the R statistics % package, but inconsistent with that of the statistics toolbox from % Matlab. % @end deftypefn
