There are several ways to fit the given data to a custom model in MATLAB. If you have the curve fitting toolbox, then you can use fit(): https://www.mathworks.com/help/releases/R2020a/curvefit/fit.html
Alternatively, you can also use functions from the optimization toolbox
lsqcurvefit(): https://www.mathworks.com/help/releases/R2020a/optim/ug/lsqcurvefit.html
lsqnonlin(): https://www.mathworks.com/help/releases/R2020a/optim/ug/lsqnonlin.html
The exact solution depends on your dataset and the function.
