Dear community,
I am trying to split a 50000x2 data in .mat into 100 equal-sized 500x2 data (that will allow me to plot 100 figures afterwards)
Wish to get help from you all.
Thank you.

This code shows an example of how it can be done
M = rand(50000,2);
C = mat2cell(M, 500*ones(100,1), 2);
figure()
for i = 1:numel(C)
subplot(10,10,i)
plot(C{i}(:,1), C{i}(:,2))
end

One way is to use mat2tiles. For example
A=rand(50000,2);
Asplit=mat2tiles(A,[500,2]);
whos A Asplit
Name Size Bytes Class Attributes
A 50000x2 800000 double
Asplit 100x1 811200 cell
