scipy.integrate.dblquad¶
- scipy.integrate.dblquad(func, a, b, gfun, hfun, args=(), epsabs=1.49e-08, epsrel=1.49e-08)[source]¶
Compute a double integral.
Return the double (definite) integral of func(y, x) from x = a..b and y = gfun(x)..hfun(x).
Parameters: func : callable
A Python function or method of at least two variables: y must be the first argument and x the second argument.
a, b : float
The limits of integration in x: a < b
gfun : callable
The lower boundary curve in y which is a function taking a single floating point argument (x) and returning a floating point result: a lambda function can be useful here.
hfun : callable
The upper boundary curve in y (same requirements as gfun).
args : sequence, optional
Extra arguments to pass to func.
epsabs : float, optional
Absolute tolerance passed directly to the inner 1-D quadrature integration. Default is 1.49e-8.
epsrel : float, optional
Relative tolerance of the inner 1-D integrals. Default is 1.49e-8.
Returns: y : float
The resultant integral.
abserr : float
An estimate of the error.
