allan.m calculates the standard Allan deviation (ADEV) of a time domain signal. It is designed for stability analysis of frequency data, although the analysis can be applied to other types of data. Fractional frequency or phase data sets with sample rate or time stamp information are handled.
Note: for overlapping and modified Allan deviation analysis, please see the files allan_modified.m (ID: #26637) and allan_overlap.m (ID: #26441).
