MATLAB: Problem in while loop

for loop

I wrote a loop code in matlab the problem is the answer I got is for the last element of the loop V =[0.0312 + 0.2251i 0.0312 – 0.2251i -0.4103 -0.0103 -0.6718 -0.6718 0.7873 0.1565 0.1714 + 0.1472i 0.1714 – 0.1472i -0.2127 -0.0645 -0.5006 + 0.4421i -0.5006 – 0.4421i 0.4082 0.9855 ]
j=1; [m n]=size(V); b=zeros(n,n);
while (j <= n)
    if isreal(V(:,n))==0
        b(:,n)=real(V(:,n))
        b(:,n+1)=imag(V(:,n))
        j=j+1
    else
        b(:,n)=V(:,n) 
    end
    j=j+1
end

Best Answer

You should be using
b(:,j) = V(:,j)
not n in your loop, which also should probably be a for loop, but that's a side issue - a while still works. And obviously all the other places you are using n instead of j too
