关于:
numpy.linspace(开始,停止,num = 50,端点= True,retstep = False,dtype = None):以间隔间隔均匀地返回数字空间。与arange类似,但不使用step而是使用样本编号。
参数:
-> start : [optional] start of interval range. By default start = 0 -> stop : end of interval range -> restep : If True, return (samples, step). By deflut restep = False -> num : [int, optional] No. of samples to generate -> dtype : type of output array
返回:
-> ndarray -> step : [float, optional], if restep = True
代码1:解释linspace函数
# 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))
输出:
B (array([ 2. , 2.25, 2.5 , 2.75, 3. ]), 0.25) A [ 0. 0.22039774 0.42995636 0.6183698 0.77637192 0.8961922 0.9719379 0.99988386 0.9786557 0.90929743]
代码2:使用matplotlib模块的numpy.linspace()的图形表示-pylab
# Graphical Represenation of numpy.linspace()
import numpy as geek
import pylab as p
# Start = 0
# End = 2
# Samples to generate = 10
x1 = geek.linspace(0, 2, 10, endpoint = False)
y1 = geek.ones(10)
p.plot(x1, y1, '*')
p.xlim(-0.2, 1.8)
输出:
代码3:使用pylab的numpy.linspace()的图形表示
# Graphical Represenation of numpy.linspace()
import numpy as geek
import pylab as p
# Start = 0
# End = 2
# Samples to generate = 15
x1 = geek.linspace(0, 2, 15, endpoint = True)
y1 = geek.zeros(15)
p.plot(x1, y1, 'o')
p.xlim(-0.2, 2.1)
输出:
