How can I save multiple matrices from text file?

I want to read dynamically all the particle path information for each particle. The number of matrices I need will vary according to how many particles are in the simulation. I separated the matrices with the word "Particle" as shown in the results.txt file I am attaching here.

Thank you in advance!

There are many ways to do this, here is one option:

contents = fileread('results.txt');  %read whole file at once
contents = strsplit(contents, 'Particle');  %split into cell array at particle
particles = cellfun(@(c) sscanf(c, '%f', [3 Inf])', contents(2:end), 'UniformOutput', false); %scan each section into a 3xN matrix

That did it! Thank you so much!
