Fast Approximate Inverse Medium Solver (full implementation, 5 000 lines of Matlab). The inverse problem is formulated with a Lippmann-Schwinger integral equation (Born Approximation). We use a SVD to solve the 3-D inverse problem. The direct computation of the SVD would be too expensive if a lot of data needs to be combined. We have proposed a method based on the coupling of a randomized SVD and a recursive SVD to reduce CPU time and memory requirements.
