The numpy.linspace function in Python is used to create arrays with evenly spaced values over a specified range. It is particularly useful for generating sequences of numbers for plotting or numerical analysis. The function takes three main arguments: start, stop, and num.

• start: The starting value of the sequence.

• stop: The end value of the sequence.

• num: The number of samples to generate.

Additionally, it has optional parameters like endpoint, which determines whether the stop value is included in the sequence, and retstep, which returns the spacing between values if set to True.

For example, numpy.linspace(0, 10, 5) generates an array [0., 2.5, 5., 7.5, 10.]. This function is highly efficient for creating arrays for mathematical computations, simulations, and visualizations.
