This function is designed to calculate a "Loss Factor" of Elbow in the pipe equipment consisted of Venturi meter, Orifice meter and Rotameter.
and the input data is like pictures below.

and the output from matlab is [-0.0720, 1.3425, 0.7478].
But it was a quite weird conclusion for me so I recalculated it by mobile calculator.
And my calculator made a result of -1.1168 for the first element of the matrix.
-0.0720 and -1.1168 are quite different from each other but I couldn't find what is the problem.
Though there was some strange results above this one, it is too large number so I can't tolerate it.
Plz take a look for my code and find some errors for me.TT

Clearly, you have misplaced any bracket or operator while solving the problem in the calculator. Look for them.
I t could even be possible that you have written the equation in a wrong way. Please recheck the hand equations and teh equations written in the script.
The result would be same if there are no misplacements.
