`np.linspace` is a function in the NumPy library that returns evenly spaced numbers over a specified interval. It takes three arguments: the starting value of the interval, the ending value of the interval, and the number of points to be generated.
For example, `np.linspace(0, 1, 5)` will generate five evenly spaced numbers between 0 and 1: `[0. , 0.25, 0.5 , 0.75, 1. ]`.
This function is commonly used in scientific computing and data analysis to create arrays of data for plotting and numerical calculations.

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. ]
```
