Forget about loops, the simple and efficient MATLAB approach is to use logical indexing:
g = y(y>0.001)
copying specific elements of an array to another.

Hi, I want to copy certain values from an array with a known size to an array with an unspesified size based on the critaria.
for i=1:length(y)
if abs(y(i))>0.001
y(i)=g(i);
end
end
So basically, I want to get all values in the array y that are greater than 0.001 to be copied into a seperate array g, but I'm struggling. Thanks in advance!

y = reshape(randn(3)/100,1,[]);
idx = 0;
forcol = 1:1:size(y,2)
if(y(col) > 0.001)
idx = idx+1;
g(idx) = y(col);% store values > 0.001 in g
end
end
fprintf('y: ')
fprintf('%f ', y)% original data
fprintf('\ng: ')
fprintf('%f ', g)% values > 0.001
