Integral

Calculate numeric and symbolic integrals

An integral is a mathematical result that represents the area between a function and a plane (e.g., x-y plane). The concept of integrals is fundamental in calculus, and has broad application in all engineering disciplines.

You can calculate integrals numerically and symbolically with MATLAB products. MATLAB includes functions for computing definite integrals numerically using techniques such as Simpson quadrature, Lobatto quadrature, and Gauss-Kronrod quadrature.

Symbolic Math Toolbox, an add-on product for MATLAB, provides additional functionality for calculating definite and indefinite integrals symbolically.
