“…The iterative process starts at the measurement signal
, and terminates when the relative change between successive iterative falls below
, that is,
Now, the csIAHDFPM and csILBFGS are applied to solve the sparse signal restoration problems, and we compare them with the PDY
25 (Algorithm 2.1) , IHCGPM
12 (Algorithm 1) and IRTTCGPM
13 (Algorithm 2.2) , whose parameters are the same as their original papers, respectively. The codes are written in Matlab R2021b 64‐bit.…”
