Sum of sines optimized starting points

Dear community,
Matlab uses optimized starting points to fit a sum of sines model to data in the Curve Fitting Toolbox.
Does somebody know the algorithm MATLAB uses to determine the starting points? I have a slightly different sines model, but the optimized starting points are not available for custom equations.
Best regards,

If your problem is linear in the fitting parameters (which is usually the case for a sum of sines), you don't need initial values for the parameters. You can directly determine the parameters in one step by solving an overdetermined linear system of equations.
