Hi, I would like to write an if statement where if RTcout<Ta , RTcout=Ta. The difficulty im having is that Ta has not been defined in the script but has been subbed into equations. Below is an example of the code:
Tcout1 = (subs(Tcout,{J,Ta,Vw},{numData1(2:25,6)',numData1(2:25,8)',numData1(2:25,12)'}));
RTcout = real(Tcout1);
Any help would be appreciated.

Do the threshold operation before you do the substitution:
numData = randi(500, 1, 10); % Original Data
JData = numData; % Create New Data Vector
JData(Jdata < 200) = 0; % Threshold Or Substitute Data
syms a b J
v = a*b + J;
vnew = subs(v, {J,a,b},{numData', randi(9,1,10)',randi(9,1,10)'}) % Substitute Thresholded Data
It would be more illustrative with your code and data, however we do not have enough of that to use.
