1) download and zip the file

2) add the directory \FCSA MRI 1.0 and all of its sub-directories into the matlab path. 

To correctly show the results of SparseMRI, you should run installMEX.m first in the 
directory \FCSA MRI 1.0\SparseMRI\WAVELAB850\
Otherwise, the SparseMRI will too slow.

3) Run Main_Run_Fig2 to obtain the Figure 2 in the paper. 
   Run Main_Run_Fig3 to obtain the Figure 3 in the paper. 
   Run Main_Run_Fig4 to obtain the Figure 4 in the paper.
   and so on.
