Function Synopsis

z = trapz(x,y)

Help text

TRAPZ	Trapezoidal numerical integration.
	Z = TRAPZ(X,Y) computes the integral of Y with respect to X using
	trapezoidal integration.  X and Y must be vectors of the same length,
	or X must be a column vector and Y a matrix with as many rows as X.
	TRAPZ computes the integral of each column of Y separately.
	The resulting Z is a scalar or a row vector.

	Z = TRAPZ(Y) computes the trapezoidal integral of Y assuming unit
	spacing between the data points.  To compute the integral for
	spacing different from one, multiply Z by the spacing increment.

	See also SUM, CUMSUM.
