Unidentified function or variable in Matlab cannot figure out

I'm trying to write a for loop with a counter. The counter starts at 1 and goes up to 5000. I want the function to use all the numbers up to 5000. This is what I have so far.
j = 1;
for i = 1:length(RT)
if RT(i) < 5000 ;
newRT(j) = RT(i);
j = j+1;
end
end
Is there something wrong with my code? Matlab will not display anything. It is saying the variable RT is undefined.

Nothing in your code indicates that RT is defined!

if RT were defined as an array of data, would the code work?
As in RT is an array of data and all i want is the data whose values are less than 5000.

Yes, I cannot see any problem. This code
RT = 1e4 * rand( 1, 100 );
jj = 1;
for ii = 1:length(RT)
if RT(ii) < 5000 ;
newRT(jj) = RT(ii);
jj = jj+1;
end
end
whos newRT
produce this output
Name Size Bytes Class Attributes
newRT 1x56 448 double
