allan_modified.m calculates the modified Allan deviation (MDEV) of a time domain signal. It is intended for stability analysis of frequency data. Fractional frequency or phase data sets with sample rate or time stamp information are handled.
Note: for regular and overlapping Allan deviation analysis, please see the files allan.m (ID: #13246) and allan_overlap.m (ID: #26441).

I need your help.
when I run this code I find this error:
Error using allan_modified (line 117)
Not enough input arguments.
Thanks for the feedback. I do not have a secret magic button for speeding up the code :) MDEV is more complex than ADEV, so it takes longer to calculate. If you have some ideas about how to implement the algorithm, please send me an email!
Note that all of the code in this series (allan.m, allan_overlap.m, allan_modified.m) runs much faster if you provide a sample rate than if you provide timestamps.
This program works, it's a good addition to the allan variance frequency analysis, however, it takes a very long time to calculate. Is there any way to speed it up?
