Here is a Matlab GUI multi-function signal analysis package:
Vibrationdata Signal Analysis Package

Alternate Link for Package    (Save link as)

The main script is: vibrationdata.m

The remaining scripts are supporting functions.

This is a work-in-progress. Some features are not yet installed but will be in a future revision. Please check back for updates.

The download and extraction process should be straightforward, but here are some slides for those who need instruction:  Vibrationdata_download.pptx
