matlab dryden模型,Vibrationdata Matlab Signal Analysis & Structural Dynamics Package

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

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.

Example using the GUI are given in Vibrationdata Webinars

autocorrelation & cross-correlation

Bessel, Butterworth & mean filters

Fourier transform, FFT, waterfall FFT, spectrogram

FFT for Machine Vibration ISO 10816

SRS time history synthesis

SDOF response to base input and applied force

SPL

cepstrum & auto-cepstrum

integration & differentiation
