Hi
If we declare two rows of random numbers
x = randn(2,100)
and
then use a for loop to move the numbers
for k=1:10
x = 1 0 * x
0 1
end for
This will spread the numbers from (0,0), right? But if I want the numbers to start from (10,10) and if they cross 20, reinitialize them again... is this possible?
If not with randn, can you suggest another solution?

Please post valid Matlab code to explain your problem. "for k=1:10 x = 1 0 * x 0 1 end for" is not clear.
What does "crossing 20" mathematically mean? The norm, the maximum, the minimum of the two components?

Your question is not really clear ... how about
x = mod(randn(2, 100)+10, 20)
You maybe you mean ...
x = 10*randn(2, 100)+10;
while any(x(:) > 20)
x(x(:) > 20) = 10*randn(sum(x(:) > 20), 1)+10;
end
