I have to fit the T value to the measured T value.

Maybe I am misunderstanding the task, but if you have T measured, you can calculate dT/dt with just

y = diff (T) / samplingrate;

Now you have your lefthand side (it's one element shorter than T, handle this in a sensible way, e.g. by appending something to y or discarding one element from T later on) and might be able to use leasqr as before.
