--> The folder 'RUDUR_Algo/' contains the RUDUR algorithm's MATLAB files. 


---------------------------------------------------------
-------------------------- DEMO -------------------------

	--> A Demo is available in the script 'Demo_toyExample.m' to test RUDUR on the toy example.
	--> You can modify parameters of the dataset (background/no background, Noise)
	--> You can also modify parameters of RUDUR (alpha, beta, gamma, mu)
