np.linspace

Numpy's linspace() function is used to create an array of evenly spaced numbers within a specified interval. It takes three arguments - start, stop, and num.
The start argument specifies the starting value of the sequence, the stop argument specifies the end value, and the num argument specifies the number of evenly spaced numbers to generate between the start and stop values.
For example, np.linspace(0, 10, 5) will generate an array containing 5 evenly spaced numbers between 0 and 10, including both 0 and 10. The output would be [0., 2.5, 5., 7.5, 10.].
np.linspace() is often used for plotting graphs and creating numeric sequences.

NP.linspace
NP.linspace是NumPy库中的一个函数,用于在指定的间隔内返回均匀间隔的数字。它的语法如下:
```python
numpy.linspace(start, stop, num=50, endpoint=True, retstep=False, dtype=None, axis=0)
```
其中,参数的含义如下:
- start:序列的起始值
- stop:序列的结束值
- num:生成的样本数,默认为50
- endpoint:序列中是否包含stop值,默认为True
- retstep:如果为True,返回样本之间的间距
- dtype:输出数组的数据类型
- axis:沿着哪个轴生成样本,默认为0
举个例子,如果我们想要在0到10之间生成5个数字,可以这样写:
```python
import numpy as np
x = np.linspace(0, 10, 5)
print(x)
```
输出结果为:
```
[ 0. 2.5 5. 7.5 10. ]
```
