After 10000 trajectories of a stochastic differential equation of 55 steps, I get a 10000*55 matrix of results. At present, I want to choose top 5% and bottom 5% of the results in each step, but I do not know which code could help me finish this. Would anyone please help me? Thanks a lot.

Accepted answer
% Rounded 5%
pt = round(10000*0.05);
% Sort (each column) and take top and bottom 5%
A = sort(A); top5 = A(1:pt,:); bot5 = A(end-pt+1:end,:);
