# 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

## Description

Constructs a PolySystem from the given polynomials.

    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
