% Cumulative numerical integration using trapezoidal method.
% @code{cumtrapz (@var{y})} computes the cumulative integral of the
% @var{y} along the first non-singleton dimension. If the argument
% @var{x} is omitted a equally spaced vector is assumed. @code{cumtrapz
% (@var{x}, @var{y})} evaluates the cumulative integral with respect
% to @var{x}.
