SciPy Python的科学计算包

SciPy (pronounced "Sigh PIE") 是一个开源的数学、科学和工程计算包。

示例代码：

from scipy import optimize, SPEcial
from NumPy import *
from pylab import *
 
x = arange(0,10,0.01)
 
for k in arange(0.5,5.5):
     y = special.jv(k,x)
     plot(x,y)
     f = lambda x: -special.jv(k,x)
     x_max = optimize.fminbound(f,0,6)
     plot([x_max], [special.jv(k,x_max)],'ro')
