The `numpy.trapz()`

function in NumPy is used to perform integration along a given axis by using the composite trapezoidal rule.

numpy.trapz(y, x=None, dx=1.0, axis=- 1)

Syntax for the numpy.trapz() function

The `numpy.trapz()`

function takes the following parameter values:

`y`

: This is the input array to be integrated. This is a required parameter.`x`

: This is the given sample points that corresponds to the`y`

values. This is an optional parameter.`dx`

: This is the spacing provided between the sample points when`x`

is None. The default value is`1`

. This is an optional parameter.`axis`

: This represents the angle along which the integration is done.

import numpy as np# creating the input array to be integratedmyarray = np.array([1,2,3])# creating the sample pointsx = np.array([4, 6, 8])# implementing the numpy.trapz() functionintarray = np.trapz(myarray, x)print(intarray)

Implementing the numpy.trapz() function

- Line 1: We import the
`numpy`

module. - Line 4: We create an input array
`myarray`

using the`array()`

function. - Line 7: We create an array
`x`

containing the sample points using the`array()`

function. - Line 10: We implement the
`numpy.trapz()`

function on the arrays and assign the result to a variable`intarray`

. - Line 12: We print the variable
`intarray`

.
