You're running 96256 total loops which will take a while. It looks like you terminated the process while waiting.
To see the progress during execution, use waitbars. They will add slightly to the processing time but the benefit is that 1) you know it's working, 2) you can see how far the progress is, and 3) if there is an error, you can see exactly where in the loop(s) the error ocurred.
wb1 = waitbar(0,'i loop 0/376');
wb2 = waitbar(0,'j loop 0/256');
wb2.Position(2) = wb1.Position(2)-wb2.Position(4)-30; %put waitbar 2 under wb1
for i = 1:376
waitbar(i/376,wb1,sprintf('i loop %d/376',i))
for j = 1:256
waitbar(j/256,wb2,sprintf('j loop %d/256',j))
Noise = 5*randn(1,length(t1));
Decrease_Factor = 356; %if this is really a constant, move it out of the loop!
Dec_NSignal = decimate(Noise,Decrease_Factor);
Dec_NSignal2 = decimate(Dec_NSignal,3);
N(i,j,1:100) = Dec_NSignal2;
end
end
delete([wb1,wb2])
Also, properly allocate the N variable.
N = zeros(376,256,100);
