how to shuffle a dataset in matlab in matlab

To shuffle a dataset in Matlab, you can use the randperm function to generate a random permutation of the data indices and then use this permutation to shuffle the dataset. Here's an example code snippet:

main.m
% Example dataset
dataset = rand(10, 3);

% Get random permutation of indices
n = size(dataset, 1);
perm = randperm(n);

% Shuffle dataset
shuffled_dataset = dataset(perm, :);
176 chars
10 lines

In this example, we first generate a random 10x3 dataset using the rand function. We then use the randperm function to generate a random permutation of the indices 1 to 10. Finally, we use this permutation to index into the original dataset and create a shuffled version of the dataset.

Note that you can modify this code snippet to work with different sizes and types of datasets in Matlab.
