These codes realize data transformation and simple data processing for fault diagnosis.
If you want to analysis the data automatically, we need Setting the parameters in Pars_Seeting!!!!!!!!
If you want to analysis the data one by one, we should use the file with single!!!!!!!!
% The code will only test on matlab2016b.

Additionally!!!
We will continue to add new algorithms to the this codebook for furthering vibration signal processing.
