polySystem -- construct a polynomial system

• Usage:

  P = polysystem F

• Inputs:
  • F, a list or an ideal or a matrix (column matrix) with polynomial entries or a polynomial system
• Outputs:
  • P, a polynomial system

i1 : R = CC[x,y]; S := polySystem {x^2+y^2-6, 2*x^2-y}

o2 = {-2} | x2+y2-6 |
     {-2} | 2x2-y   |

o2 : PolySystem

i3 : S = polySystem transpose matrix {{x^2+y^2-6, 2*x^2-y}}

o3 = {-2} | x2+y2-6 |
     {-2} | 2x2-y   |

o3 : PolySystem

i4 : T = polySystem S

o4 = T

o4 : PolySystem
