You can save them into a cell as shown below.
iwant = cell([],1) ; % initilize a cell array;
while(fin)
% made seperate matrix for the test
for i=1:length(pts)
matrix = [x(next:pts(i,:)), y(next:pts(i,:)), test(next:pts(i,:))];
next = pts(i);
iwant{i} = matrix ; % save into a cell
end
if pts(i) == length(pts)
fin = 0;
end
return
end
Access the cell using: iwant{1}, iwant{2},...etc.
You can also initialize it into amatrix, if dimensions are known in prior and if dimensions don't change in a loop.
