% Numerical integration using trapezoidal method. @code{trapz
% (@var{y})} computes the 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{trapz (@var{x}, @var{y})}
% evaluates the integral with respect to @var{x}.
