MATLAB: How to save for loop values

Question

f=zeros(1,M);

for i=1:M

f(i)=fd+((1+m(i)*r)/2)*f_delta;

f(i)=fd-((1+m(i)*r)/2)*f_delta;

end

I need to save both values for the addition and subtraction.

Thanks in advance.

Answer 1

Try this:

f=zeros(2,M);
for i=1:M
    f(:,i)=[fd+((1+m(i)*r)/2)*f_delta; fd-((1+m(i)*r)/2)*f_delta];
end

That saves them as different rows of a (2xM) matrix.
