Matlab, t-SNE dimensionality reduction visualization

Matlab, t-SNE dimensionality reduction visualization source code.
The program comments are detailed, simple and easy to understand, making it very convenient to replace data.
The example data is in Excel format, consisting of 80 rows and 17 columns, with a total of 80 samples. The first 16 columns are feature values and the last column is labels, with a total of 4 categories.
When replacing data, the number of samples and features can be arbitrarily specified, and the number of categories can also be arbitrarily specified.
