There are many curve fitting and interpolation tools like polyfit (or even this nice logfit toolbox I found here), but I can\'t seem to find anything that will fit a sigmo

    I would suggest you use MATLAB's Global Optimization Toolbox, and in particular the Genetic Algorithm Solver, which you can use for your problem by optimizing (= finding the best fit for your data) the sigmoid function's parameters through genetic algorithm. It has a GUI that is easy to use.
