proximity

weights for first set of constraints

weights for second set of constraints

list of projection functions for first set of constraints; each takes a single point and returns its projection

plist1

list of projection functions for second set of constraints; each takes a single point and returns its projection

plist2

Function handle for output mapping

<code>proximity</code> computes the proximity function.

An implementation of the majorization-minimization (MM) algorithm introduced by
Xu, Chi, Yang, and Lange (2017) <arXiv:1612.05614> for solving multi-set split feasibility problems. In the multi-set split feasibility problem, we seek to find a point x
in the intersection of multiple closed sets and whose image under a mapping also must fall in the intersection of several closed sets.
