GeLMA is an algorithm to solve an underdetermined linear system
Ax=b, when x is sparse. Its convergence analysis was discussed in
this paper. You will also need
In the paper Illumination strategies for intensity-only imaging, we used this file to generate data.
It is the main file of the
algorithm to image sparse scatterers in homogeneous media with amplitude measurements only.
Run it in command line in MATLAB. You will need two additional files:
the GeLMA subroutine and the initialization.
