# NonLinearSolvePackage RΒΆ

nlinsol.spad line 63 [edit on github]

NonLinearSolvePackage is an interface to SystemSolvePackage that attempts to retract the coefficients of the equations before solving. The solutions are given in the algebraic closure of `R`

whenever possible.

- solve: (List Polynomial R, List Symbol) -> List List Equation Fraction Polynomial R
`solve(lp, lv)`

finds the solutions in the algebraic closure of`R`

of the list`lp`

of rational functions with respect to the list of symbols`lv`

.

- solve: List Polynomial R -> List List Equation Fraction Polynomial R
`solve(lp)`

finds the solution in the algebraic closure of`R`

of the list`lp`

of rational functions with respect to all the symbols appearing in`lp`

.

- solveInField: (List Polynomial R, List Symbol) -> List List Equation Fraction Polynomial R
`solveInField(lp, lv)`

finds the solutions of the list`lp`

of rational functions with respect to the list of symbols`lv`

.

- solveInField: List Polynomial R -> List List Equation Fraction Polynomial R
`solveInField(lp)`

finds the solution of the list`lp`

of rational functions with respect to all the symbols appearing in`lp`
