Algorithms
lsqnonneg
uses the algorithm described in [1]. The algorithm starts
with a set of possible basis vectors and computes the associated dual
vector lambda
. It then selects the basis vector
corresponding to the maximum value in lambda
to
swap it out of the basis in exchange for another possible candidate.
This continues until lambda ≤ 0
.
