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.
# import scipy.integrate from scipy import integrate func = lambda x: x * * 3 # using scipy.integrate.fixed_quad() method gfg = integrate.fixed_quad(func, 0.0 , 1.0 , n = 2 ) # n is the order of integration print (gfg) |
Output :
0.24999999999999997
Example #2 :
# import scipy.integrate from scipy import integrate func = lambda x: x * * 2 + 4 * x + 4 # using scipy.integrate.fixed_quad() method gfg = integrate.fixed_quad(func, 1.0 , 2.0 , n = 2 ) # n is the order of integration print (gfg) |
Output :
12.333333333333332
