In the world of data science, arrays play a vital role as they allow for efficient computation and management of large quantities of data. Numpy is a popular library in Python for working with arrays, and it includes powerful tools for exploring multidimensional ranges. This article will compare two of Numpy’s most important functions for dealing with multidimensional ranges: linspace and meshgrid.

Linspace Function

The linspace function is used to create evenly spaced arrays between two given points. It allows users to specify the number of elements they want in the output array, including both the start and endpoint. For example, the following code uses linspace to create an array with 10 equally spaced values between 0 and 1:

import numpy as npx = np.linspace(0, 1, 10)print(x)

The output of this code will be:

[ 0.          0.11111111  0.22222222  0.33333333  0.44444444  0.55555556  0.66666667  0.77777778  0.88888889  1.        ]

Meshgrid Function

The meshgrid function is used to create a grid of coordinates that cover a specific range. It takes two input 1D arrays and produces two output 2D arrays that represent all possible combinations of values between the inputs. For example, the following code creates a grid of points covering a 2D range from -1 to 1:

import numpy as npx = np.linspace(-1, 1, 5)y = np.linspace(-1, 1, 5)X, Y = np.meshgrid(x, y)print(X)print(Y)

The output of this code will be:

[[-1.  -0.5  0.   0.5  1. ] [-1.  -0.5  0.   0.5  1. ] [-1.  -0.5  0.   0.5  1. ] [-1.  -0.5  0.   0.5  1. ] [-1.  -0.5  0.   0.5  1. ]][[-1. -1. -1. -1. -1.] [-0.5 -0.5 -0.5 -0.5 -0.5] [ 0.   0.   0.   0.   0. ] [ 0.5  0.5  0.5  0.5  0.5] [ 1.   1.   1.   1.   1. ]]

Range Coverage

One important difference between linspace and meshgrid is the way they cover a range. The linspace function creates a linear spacing between the start and end points, whereas the meshgrid function creates a complete grid of all possible combinations between the two inputs.

Linspace Range Coverage Example

If we look at the previous example, we can see that the linspace function covers the range from 0 to 1 by creating equal distance partitions between the endpoints:

[-1.  -0.5  0.   0.5  1. ]

Meshgrid Range Coverage Example

The meshgrid function, on the other hand, creates a full grid of coordinate pairs that cover the entire range defined by x and y:

[-1.  -0.5  0.   0.5  1. ][-1.  -0.5  0.   0.5  1. ]

Grid Structure

The structure of the output from linspace and meshgrid also differs. The linspace function returns a 1D array, whereas the meshgrid function returns two 2D arrays. The two outputs from meshgrid are arranged in a grid structure where one array represents the x-coordinates and the other represents the y-coordinates of each point in the grid. This grid structure makes it easy to plot data using tools like Matplotlib.

Number of Dimensions

The final difference between linspace and meshgrid is their number of dimensions. The linspace function produces exactly one dimension, whereas the meshgrid function produces a two-dimensional output. This means that meshgrid is better suited for working with higher dimensional data.


Overall, both linspace and meshgrid are incredibly useful tools for exploring multidimensional ranges in Numpy. The choice between them ultimately depends on the specific needs of the user. If you need evenly spaced values along a linear range, then linspace is the way to go. However, if you want to create a full grid of coordinates across a range, then meshgrid is the better choice. Both functions have their unique strengths, and being familiar with them will allow you to take advantage of the powerful array handling capabilities of Numpy.

Property Linspace Meshgrid
Coverage Type Linear Partitioning Full Grid of Coordinates
Output Structure 1D Array Two 2D Arrays in a Grid Structure
Number of Dimensions 1D 2D
