How to plot with t-SNE in MATLAB from 5 elements composition into 2 dimensions?

I would like to make a figure like the below figure!

T-distributed stochastic neighbor embedding (t-SNE) used in the figure to visualize across the composition space in two dimensions (I have a 5 element composition space for the alloy and entropy of mixing calculate from the composition).

Entropy of mixing=;

We have the data for the entropy of mixing and compositions in the Excel attached file.

My question is now how to visualize from composition space with 5 elements into just two dimensions! The results should be like a pentagon, because the attached picture is for a 6 elements alloy and is like a hexagon.

P.mat attached matrix contains x1,x2,x3,x4,x5,.

How to make a t-SNE from P matrix?

The data is big so I cannot attached them here.

If anyone can solve the problem, I can send the data by email.
