Is it possible to write an automated code using the Curve Fitting Toolbox to fit data to a customized function? Example
clc
format short e
x = xdata
y = ydata;
f = fit(x,y,'Desired_Function')
plot(f,x,y)
Where desired function is something outside the usual default functions of Matlab. I usually need to make a fitting inside a bigger program and the fitting functions go beyond what Matlab offers in its library.

You can supply an arbitrary anonymous function as fittype:
