How can I access the previous index of a vector?

Hello friends,
I am trying to write a code to generate random vectors. Some of the variables are integer whereas a few are real numbers. Following is the code:
xL=[1 500 1 500];
xU=[37 1400 37 1400];
Xint=[1 3];
nvar=4;
for xV=1:nvar
if Xint(xV)==xV
InPoP(:,xV) = randi([xL(xV) xU(xV)],Popu_size,1);
else
InPoP(:,xV) = (xU(xV)-xL(xV)).*rand(Popu_size,1) + xL(xV);
end
end
Xint vector shows that first and third elements should be generated as integer. The problem is when the loop moves away from x=2. It cannot access the elements of Xint to know the number. I would be grateful if someone can share the solution of the problem.
Regards

You have in Xint only two numbers and you are trying to access four numbers out of it. Make Xint to have four numbers i.e include few more numbers.

You don’t appear to use ‘Xint’ for any other purpose than deciding whether to use integers or reals. Therefore I suggest you change it to:
Xint = [1 0 1 0];
for xV=1:nvar
if Xint(xV) == 1
% Use integers
else
% Use reals
end
