Gini index (GI) is an outstanding sparsity index which has been widely applied in machinery fault diagnosis. It has been verified that GI has the most stable gradient property and has the best ability to distinguish impulsiveness and repetitive transients compared with the most-used sparsity indexes, such as kurtosis, Lp/Lq norm, etc. To guide the application of GI in this field, some Matlab codes are provided. There are the codes of GI, GI-based indexes, improved methods based on GI and the deconvolution methods based on GI.
The matlab codes of GI and GI-based indexes permit to reproduce some results in the papers:
