High-precision numerical integration is implemented in the vpaintegral function of the Symbolic Math Toolbox™. vpaintegral uses variable-precision arithmetic in contrast to the MATLAB integral function, …

This MATLAB function numerically integrates function fun from xmin to xmax using global adaptive quadrature and default error tolerances.

Find the indefinite integrals of the multivariate expression with respect to the variables x and z.

Numerical integration functions can approximate the value of an integral whether or not the functional expression is known:

The integral family only accepts function handles as inputs, so those functions cannot be used with discrete data sets. Use trapz or cumtrapz when a functional expression is not available for integration.

This example shows how to compute definite integrals using Symbolic Math Toolbox™.

Learn about numeric and symbolic integrals and how to apply them to a broad range of engineering applications. Resources include videos, examples, and documentation.

Evaluate the integral over the region 0 ≤ x ≤ 5 and −5 ≤ y ≤ 0. Specify the 'iterated' method and approximately 10 significant digits of accuracy.

This MATLAB function computes the approximate integral of Y via the trapezoidal method with unit spacing.
