What is the purpose of the linspace() function in NumPy?

a) To create an array with a specified number of evenly spaced values between a start and stop value

b) To generate random values within a specified range

c) To create an array of ones

d) To find the minimum and maximum values in an array

Answer:

a) To create an array with a specified number of evenly spaced values between a start and stop value

Explanation:

The linspace() function in NumPy is used to create an array with a specified number of evenly spaced values between a start and stop value. Unlike arange(), which uses a step size, linspace() divides the interval into the desired number of parts.

import numpy as np

# Creating an array with 5 evenly spaced values between 0 and 1
arr = np.linspace(0, 1, 5)
print(arr)  # Output: [0.   0.25 0.5  0.75 1.  ]

In this example, the linspace() function creates an array of 5 values evenly spaced between 0 and 1.

The linspace() function is useful in numerical simulations, plotting functions, and creating grids for interpolation or integration, where evenly spaced points are needed within a specific range.
