How can I fit data to a piecewise function, where the breakpoint of the function is also a parameter to be optimised?
You can also parametrize the model function directly in terms of the break point coordinates (xbreak, ybreak) and two curvature ...

Is it possible to merge excel cells without using actxserver
No, not through writecell. I've heard there are Python libraries that can do it, and there are ways to call Python from Matlab.

How can i use symbolic variables in a parallel Computing (parfor)?
Why not simply - Dlu_11_1 = reshape( jacobian(dlU_11, U1) , M*N,N,M);
