Return a tuple of coordinate matrices from coordinate vectors. Make N-D coordinate arrays for vectorized evaluations of N-D scalar/vector fields over N-D grids, given one-dimensional coordinate arrays x1, x2,…, xn. Changed in version 1.9: 1-D and 0-D cases are allowed.
In Python, the purpose of meshgrid is to help replace slow Python loops by faster vectorized operations available in NumPy library. meshgrid role is to prepare 2D arrays required by the vectorized operation.
The meshgrid () method takes two or more 1D arrays representing coordinate values and returns a rectangular grid of a pair of 2D arrays. Example. import numpy as np # 1D arrays as x and y coordinates x = np.array ( [1, 2, 3]) y = np.array ( [10, 20]) # create a 2D grid using meshgrid X, Y = np.meshgrid (x, y)
2 sie 2022 · Numpy meshgrid is a tool for numeric data manipulation in Python. We use Numpy meshgrid to create a rectangular grid of x and y values. More specifically, meshgrid creates coordinate values that enable us to construct a rectangular grid of values.
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 ().
31 sty 2021 · numpy.meshgrid (*xi, copy=True, sparse=False, indexing='xy') [source] ¶ Return coordinate matrices from coordinate vectors. Make N-D coordinate arrays for vectorized evaluations of N-D scalar/vector fields over N-D grids, given one-dimensional coordinate arrays x1, x2,…, xn.
