changeFlags(Matrix,List,Sequence) -- recursive call of change flags

Synopsis

• Function: changeFlags

• Usage:

  changeFlags(MX,SolsF,CFG)

• Inputs:
  • MX, a matrix, matrix of local coordinates
  • SolsF, a list, solutions with respect to flags F
  • CFG, a sequence, a triple (C,F,G) where C is a list of m Schubert conditions, F is a list of m flags defining an instance with solution set sols, G is a list of m flags defining the instance whose solutions we want.
• Optional inputs:
  • OneHomotopy => ..., default value true, strategy for moving solutions to a Schubert problem
• Outputs:
  • a list, solutions of the problem C with respect to flags G.
