Go back to initializing values using for loop when condition is not met

I have a for loop where I initiialize random values to variables and I check for certain condition, if my condition is not met I have to reinitialize the values for the same iteration. How do I do so?
Here's a sample
n = 100;
for i = 1:n
x(i) = rand
y(i) = rand
if(x(i)< 0 || y(i)<0)
disp(' I need to reinitialize values for the same i and my n count should be 100')
end
end
So I have to run the loop until I reach my 'n' value and meet my conditions within the loop. Is there a way to do it or should I use different loop like while?

Hello,
There are several ways, one approach that you can use as follows
clear
n = 100;
x = zeros(1,n);
y = zeros(1,n);
for i = 1:n
xt = rand;
yt = rand;
while (xt*yt<0)
xt = rand;
yt = rand;
end
x(i) = xt;
y(i) = yt;
end
