Before jumping into a for loop, you should consider whether it is possible to vectorize this code. MATLAB is really good at handling large vectors and matrices, and performing linear algebra. Think about whether your algorithm can be done on the entire data set all at once, rather than in a massive for loop.
As a first step, you may want to define your time increment as a variable, perhaps called dt, so that you can validate if it is correct. So, for example:
dt = inputBlockSize*Tb/Ts*Ts;
disp(dt);
When MATLAB displays the value of dt, does it make sense to you? Also, notice that in the equation for dt, you first divide by Ts, and then immediately multiply by Ts. Is that really necessary? It would be more efficient to eliminate these two operations entirely:
dt = inputBlockSize*Tb;
disp(dt);
Does this code result in the same value for dt as before? Does this code make sense? Is the value of dt what you were expecting, or is it surprising?
HTH.
Best,
