3.4 Integration and ODEs (scipy.integrate)
3.4.1 Integrating functions, given function object
quad(func, a, b[, args, full_output, ...]) Compute a definite integral.
dblquad(func, a, b, gfun, hfun[, args, Compute the double integral of func2d(y,x) from x=a..b and
...])
y=gfun(x)..hfun(x).
tplquad(func, a, b, gfun, hfun, qfun,
rfun)
Compute a triple (definite) integral.
fixed_quad(func, a, b[, args, n]) Compute a definite integral using fixed-order Gaussian quadrature.
quadrature(func, a, b[, args, tol, Compute a definite integral using fixed-tolerance Gaussian
maxiter, ...])
quadrature.
romberg(function, a, b[, args, tol, show,
...])
Romberg integration of a callable function or method.
quad(func, a, b, args=(), full_output=0, epsabs=1.4899999999999999e-08, epsrel=1.4899999999999999e-08,
limit=50, points=None, weight=None, wvar=None, wopts=None, maxp1=50, limlst=50)
Compute a definite integral.
Integrate func from a to b (possibly infinite interval) using a technique from the Fortran library QUADPACK.
Run scipy.integrate.quad_explain() for more information on the more esoteric inputs and outputs.
Parameters
func : function
a
b
Returns
y : float
a Python function or method to integrate.
[float] lower limit of integration (use -scipy.integrate.Inf for -infinity).
[float] upper limit of integration (use scipy.integrate.Inf for +infinity).
full_output :
non-zero to return a dictionary of integration information. If non-zero, warning
messages are also suppressed and the message is appended to the output tuple.
the integral of func from a to b.
abserr
[float] an estimate of the absolute error in the result.
infodict
[dict] a dictionary containing additional information. Run
scipy.integrate.quad_explain() for more information.
message :
a convergence message.
explain :
appended only with ‘cos’ or ‘sin’ weighting and infinite integration limits, it
contains an explanation of the codes in infodict[’ierlst’]
