A linear system solver that takes into account intersection angle

  1. May 28, 2010 #1
    Hello

    An example: let there be a four linear equations system with two unknowns.

    Let the solutions of the equations create together something like the # sign.

    Is there a solver that takes into account only the four ~90deg crossings in the center, and returns the solution being the average of respective four points, but:

    completely ignores the crossings of pairs of almost-parallel lines, as the result would likely be almost only an effect of noise and numerical errors.

    Ignore-large-value-intersections solver is not enough, as the almost-parallel lines can be so close to each other, that their crossing point can
    be near the "sensible" solutions.
