okay so i have my final answer that is after solving a system of linear equation my answer should be a matrix of 3x1 that is the values of x,y and z respectively. so what i want to know is how do i display that in a form of matrix where the number of rows represents the variables and the number columns represents the number of iteraions, i which is also included in my calculator

format long g
for i = 1 : 10
%x0 = some calculation involving values indexed at i that gives a vector of length 3
x0 = [sin(2*pi*i+i/2), -cos(2*pi*i-i/2), cos(2*pi*i+i/2)*sin(2*pi*i-i/2)];
results(:,i) = x0;
end
disp(results)
