Mathematics plays a significant role in modern-day science and technology. Several mathematical functions have become the backbone of machine learning, data analytics, and scientific research.

Some frequently used mathematical functions are np.linspace() and np.arange(). They are both functions used in generating values of arrays in scientific computing.

However, there are specific differences between them. In this article, we will discuss the differences between np.linspace() and np.arange(), and we will provide examples on how to use them effectively.

## 1) Differences Between np.linspace() and np.arange()

np.linspace() and np.arange() both generate values that are used to create arrays in scientific computing. However, they differ in their specific uses.

Firstly, np.linspace() generates evenly-spaced values between two given endpoints. In contrast, np.arange() generates equally spaced values within a specified interval with a user-defined step size.

Secondly, np.linspace() requires the number of samples that you want to generate between the intervals, whereas np.arange() only requires a start, stop, and step value.

## 2) Example 1: How to Use np.linspace()

In this section, we will discuss how to use np.linspace() and create values using it.

The np.linspace() function has a simple syntax that requires the start and stop arguments that specify the range of values desired and the ‘num’ argument that specifies the number of samples to generate. For example, suppose we want to generate six evenly spaced values between 0 and 1.

### We could write the following code snippet:

```
import numpy as np
values = np.linspace(start=0, stop=1, num=6)
print(values)
```

### The output of the code would be an array that contains six evenly spaced values between 0 and 1 as follows:

```
[ 0. 0.2 0.4 0.6 0.8 1. ]
```

We can see that the np.linspace() function has successfully created an array of six evenly spaced values between 0 and 1.

## 3) Example 2: How to Use np.arange()

In this section, we will go into more detail on how to use np.arange() and create values using it. The np.arange() function has a straightforward syntax that requires the start and stop arguments that specify the range of values desired and the step argument that specifies the discrete increment between values.

For example, suppose we want to generate values between 5 and 15 at an increment of 2. We could write the following code snippet:

```
import numpy as np
values = np.arange(start=5, stop=15, step=2)
print(values)
```

The output of the code would be an array that contains spaced values, which are 5, 7, 9, 11, and 13.

```
[ 5 7 9 11 13]
```

We can see that the np.arange() function has successfully created an array that contains spaced values between 5 and 15 at a step of 2.

Using np.arange(), it is also possible to create arrays by setting only the start and stop values, which will assume a default increment of 1. We could write the following code snippet:

```
import numpy as np
values = np.arange(start=5, stop=15)
print(values)
```

The output of the code would be an array that contains spaced values, which are 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14.

```
[ 5 6 7 8 9 10 11 12 13 14]
```

We can see that the np.arange() function has successfully created an array that contains spaced values between 5 and 15 at a step of 1 by default.
