gf_levelset_set — General function for modification of LEVELSET objects.
I = gf_levelset_set(LS, ...)
General function for modification of LEVELSET objects.
gf_levelset_set(LS,'values',list(mat v1|string poly1)[, list(mat
    v2|string poly2)]) Set values of the vector of dof for the level-set
    functions. Set the primary function with the vector of dof
    v1 (or the polynomial expression
    poly1) and the secondary function (if any) with the
    vector of dof v2 (or the polynomial expression
    poly2).
gf_levelset_set(LS,'simplify'[scalar eps=0.01]) Simplify dof of
    level-set optionally with the parameter eps.
