With the help of scipy.integrate.fixed_quad()
method, we can get the computation of a definite integral using fixed order gaussian quadrature by using scipy.integrate.fixed_quad()
method.
Syntax : scipy.integrate.fixed_quad(func, a, b, n)
Return : Return the computed value of a definite integral.
Example #1 :
In this example we can see that by using scipy.integrate.fixed_quad()
method, we are able to get the definite integral using fixed order gaussian quadrature by using this method.
from scipy import integrate
func = lambda x: x * * 3
gfg = integrate.fixed_quad(func, 0.0 , 1.0 , n = 2 )
print (gfg)
|
Output :
0.24999999999999997
Example #2 :
from scipy import integrate
func = lambda x: x * * 2 + 4 * x + 4
gfg = integrate.fixed_quad(func, 1.0 , 2.0 , n = 2 )
print (gfg)
|
Output :
12.333333333333332
