28 maj 2022 · You use meshgrid () to convert the 1D vectors representing the axes into 2D arrays. You can then use those arrays in place of the x and y variables in the mathematical equation. Since X is a 2D NumPy array, you’ll get a 2D array back when you use X in np.sin ().
29 lut 2024 · With NumPy’s meshgrid function, you can easily create matrices that define the coordinates for a 2D grid. This is ideal for computing functions of two variables efficiently. Here’s an example: import numpy as np x = np.linspace (-5, 5, 11) y = np.linspace (-5, 5, 11) X, Y = np.meshgrid (x, y) Output:
The meshgrid() function does exactly what we want it to. It takes two 1D arrays that together specify a 2D grid and return two 2D arrays that specify the x and y grid values at all grid points. With those two arrays (that are the same size) we can now use array math to create our temperature array:
