The main functions:

1. ntonemaker.m: Generate real or complex multitone suited for a least-squares fit.

2. nsinefit.m: Perform the least-squares fit for a multitone.

Practical usage would be fitting a multitone measurement result.

The script nsinefit_demo.m provides some usage examples with added noise/distortion. The demo uses ntone_add_err.m for adding noise/distortion and ntone_wini to add error to the initial frequencies.
