SciPyPython 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')
