WebThe Quad function is the workhorse of SciPy’s integration functions. Numerical integration is sometimes called quadrature, hence the name. It is normally the default choice for performing single integrals of a function f (x) over a given fixed range from a to b. The general form of quad is scipy.integrate.quad (f, a, b), Where ‘f’ is the ...
