python的linspace函数

numpy.linspace(start,stop,num = 50,endpoint = True,retstep = False,dtype = None)均匀地返回数字空格。与范围类似但不是步骤而是使用样本编号。

# Python Programming illustrating
# numpy.linspace method

import numpy as geek

# restep set to True
print("B\n", geek.linspace(2.0, 3.0, num=5, retstep=True), "\n")

# To evaluate sin() in long range
x = geek.linspace(0, 2, 10)
print("A\n", geek.sin(x))在IDE上运行

输出:


(array([2.,2.25,2.5,2.75,3。]),0.25)
