create an alluvial plot in matlab

You can create an alluvial plot in MATLAB using the alluvial() function from the AlluvialDiagram package which can be installed via the add-on explorer. Here's an example code snippet:

main.m
% load example data (format: matrix where each row is a datapoint)
load('testdata.mat');

% create alluvial plot
alluvial(data, 'color', data(:,end), 'Labels', {'A' 'B' 'C' 'D'});

% optional modifications
box off % remove the axes box
colormap(jet) % change the colormap

This will create an alluvial plot for the loaded data with a color coding based on the last column of the data matrix. The Labels parameter specifies the labels for the nodes in the plot. You can customize the plot further by modifying the axis properties or using additional options provided by the alluvial() function.
