numpy.trapz¶
- numpy.trapz(y, x=None, dx=1.0, axis=-1)¶
Integrate along the given axis using the composite trapezoidal rule.
Integrate y (x) along given axis.
Parameters: y : array_like
Input array to integrate.
x : array_like, optional
If x is None, then spacing between all y elements is dx.
dx : scalar, optional
If x is None, spacing given by dx is assumed. Default is 1.
axis : int, optional
Specify the axis.
Examples
>>> np.trapz([1,2,3]) >>> 4.0 >>> np.trapz([1,2,3], [4,6,8]) >>> 8.0
