How do you concatenate all of the values generated by the following for loop to make a vector?

for i=1:3
a=exp(i)
end

Do not concatenate inside a loop if you know the final dimension in advance. Preallocate the output and assign it:

a = zeros(1,3);
for ii=1:3
a(ii) = exp(ii)
end

Also, don't use "i" (imaginary unit) because it is already in the standard matlab "library".

a = exp(1:3)
