Tensorflow.js is an open-source library that is developed by Google for running machine learning models as well as deep learning neural networks in the browser or node environment.
The .meshgrid() function is used to broadcast arguments in order to analyze on an N-D mesh. Moreover, for a 1D coordinate arrays i.e. *args, this method returns a list of outputs of an N-D coordinate arrays for analyzing expressions on an N-D mesh for a given N.
Note: This function favors cartesian ‘xy’ as well as matrix ‘ij’ indexing protocols. If the indexing parameter is fixed to the by default value i.e. ‘xy’, then the broadcasting commands for the first two measurements are exchanged.
Syntax:
tf.meshgrid(x?, y?, __2?)
Parameters:
- x: The stated tensor along with rank geq one. It is optional and can be of type tf.Tensor, TypedArray, or Array.
- y: The stated tensor along with rank geq one. It is optional and can be of type tf.Tensor, TypedArray, or Array.
- __2: It is optional parameter and is of type { indexing?: string; }.
Return Value: It returns tf.Tensor[].
Example 1: Using tensors of rank 1.
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Defining first tensor const t1 = [1, 1, 3]; // Defining second tensor const t2 = [2, 5, 4]; // Calling meshgrid() function const res = tf.meshgrid(t1, t2); // Printing output console.log(res); |
Output:
Tensor
[[1, 1, 3],
[1, 1, 3],
[1, 1, 3]],Tensor
[[2, 2, 2],
[5, 5, 5],
[4, 4, 4]]
Example 2: Using float values.
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Calling meshgrid() function with // float values const output = tf.meshgrid(2.1, 3.3); // Printing output console.log(output); |
Output:
Tensor
[[2.0999999],],Tensor
[[3.3],]
