Package dk.alexandra.fresco.stat.linearalgebra

Class LinearInverseProblem

java.lang.Object
dk.alexandra.fresco.stat.linearalgebra.LinearInverseProblem
All Implemented Interfaces:
dk.alexandra.fresco.framework.builder.Computation<ArrayList<dk.alexandra.fresco.framework.DRes<dk.alexandra.fresco.lib.fixed.SFixed>>,​dk.alexandra.fresco.framework.builder.numeric.ProtocolBuilderNumeric>
public class LinearInverseProblem
extends Object
implements dk.alexandra.fresco.framework.builder.Computation<ArrayList<dk.alexandra.fresco.framework.DRes<dk.alexandra.fresco.lib.fixed.SFixed>>,​dk.alexandra.fresco.framework.builder.numeric.ProtocolBuilderNumeric>
Solve a linear inverse problem, eg. find an x such that Ax = b where A is an mxn-matrix and b is an n-dimensional vector. If a system is overdetermined (m ≥ n), the computation will find the x minimising ||Ax - b||.
