Confidence Interval Estimation Added

The spectrum object has been enhanced with a new method for calculating confidence intervals for PSDs and mean-squared spectra.

Spurious-Free Dynamic Range (SFDR) Measurement Added

The dspdata object has been enhanced with a new method to measure spurious-free dynamic range (SFDR) for mean-squared spectra.

Local Maxima/Peak Finder Added

A new function findpeaks has been added to identify local maxima in a data vector. You can specify the minimum peak height and distance from its neighbors to limit the results. A findpeaks method has also been added to the dspdata object.
