MATLAB: Random numbers seed setting

MATLABseed

Hi,

I am using randn('seed', 1) at the beginning of my code for a simulation with 1000 replications. This is to make sure that if I rerun the simulation I'll get same results every time. But I am getting slightly different results in different runs. Can anyone help? I am using Matlab 2012a.

Best Answer

Use

a=rng;
out=randn
rng(a)
out=randn

Your loop

for n1 = [2:.01:1.5];

has its end point (1.5) greater than its start point (2), so it is never executed.

If you want a loop to count down, you must use a negative increment (e.g., -0.01) rather than a positive one.

A - your matrix (48x52)

Anew = zeros(48,48); % new matrix with size 48x48
s = size(A);
for jj = 1:s(1)
    Anew(jj,:) = interp1(1:s(2),A(jj,:),linspace(1,s(2),size(A2,2)));
end
