An instance for recovering the signal, which can be expressed as a block 5-sparse vector in terms of Ψ for different recovery methods. The solid line with pentagram markers represent the original signal, and the dotted line represents the recovered signal. a 2/0.5-analysis method. b 2/1-analysis method. c 0.5-analysis method. d 1-analysis method
