Hello everyone,

I want to fit multiple Experimental-Datasets to one Model-Equation. For example: y=3*cos(b)+a*x+u+C; x is my Input variable. b and u are different for each Dataset while w should be the same for each dataset.These 3 parameters should be fitted. C is different for each dataset but should not be fitted.

I tried to adept this solution (https://de.mathworks.com/matlabcentral/answers/1056-nonlinear-fit-to-multiple-data-sets-with-shared-parameters#comment_409777) but i failed.

So it would be very kind if someone could help me with this task.

Looking forward for some answers and thank you guys for your help!
