Python For Engineering and Scientific Computing

6.5    Numerical Integration

Numerical integration is the approximate calculation of certain integrals. Numerical methods are always used when integrals cannot be solved analytically or when only the numerical solutions are relevant. The latter is the case with engineering tasks.

SciPy provides numerous numerical integration methods in the integrate submodule, which can also compute double and triple integrals. The user is therefore free to select a method that suits their purposes. You can use the following statement to import the integrate submodule:

import scipy.integrate as integral
