I am trying to do a curve fitting on some experimental data with a custom function. I am more specifically trying to bring closer my function to the data. The function is the following one:
Every parameters of the function, except the shear rate () , can vary in order to fit best the data.
Here is a graph with the data and the function plotted with initial values:
The initial values are the following ones:
I already tried to use the curve fitting toolbox but i wasn't able to keep the look of the function.
Does anyone know how i can do that ?
Thank you for the help !
