Integrating functions, given function object¶
| quad(func, a, b[, args, full_output, ...]) | Compute a definite integral. |
| dblquad(func, a, b, gfun, hfun[, args, ...]) | Compute a double integral. |
| tplquad(func, a, b, gfun, hfun, qfun, rfun) | Compute a triple (definite) integral. |
| nquad(func, ranges[, args, opts]) | Integration over multiple variables. |
| fixed_quad(func, a, b[, args, n]) | Compute a definite integral using fixed-order Gaussian quadrature. |
| quadrature(func, a, b[, args, tol, rtol, ...]) | Compute a definite integral using fixed-tolerance Gaussian quadrature. |
| romberg(function, a, b[, args, tol, rtol, ...]) | Romberg integration of a callable function or method. |
| quad_explain([output]) | Print extra information about integrate.quad() parameters and returns. |

| IntegrationWarning | Warning on issues during integration. |
Integrating functions, given fixed samples¶
| trapz(y[, x, dx, axis]) | Integrate along the given axis using the composite trapezoidal rule. |
| cumtrapz(y[, x, dx, axis, initial]) | Cumulatively integrate y(x) using the composite trapezoidal rule. |
| simps(y[, x, dx, axis, even]) | Integrate y(x) using samples along the given axis and the composite Simpson’s rule. |
| romb(y[, dx, axis, show]) | Romberg integration using samples of a function. |
