MATLAB: Creating matrix from a for loop

for loopmatrix

I have this 'for loop' (where A a matrix from my program):
for m=symbols(1:1000)
d1=abs(m-A);
[C,I]=min(d1);
k=A(I);
end
I want from this loop to save the values of 'k' (1000 total) to a (1, 1000) matrix? How can I do this because I am getting some errors!
Thank you…

Hi athpapa,
I don't know what your "A" matrix or "symbols" matrix had, so I will just make them random numbers:
A = randi(500, 10) - 250;
symbols = randi(30,1,1000);
Now, we can make "k" as a vector of numbers (rather than just a single number). Note that I use "i" to iterate from 1:1000 so that we know which element of "k" to save our answer to:
k = zeros(1,1000);
for i = 1:1000
    m = symbols(i);
    d1=abs(m-A);
    [C,I]=min(d1(:));
    k(i) = A(I);
end
Does this do what you wanted it to do?
