SolveTools

 Engine

 Calling Sequence SolveTools:-Engine( eqns, vars, options )

Parameters

 eqns - set vars - {set,list} options - (optional) a sequence of keyword options

Options

 • allsolutions
 Return parameterized solutions for non-algebraic equations which may have infinitely many solutions (default is false)
 • conditionalsolutions
 Return piecewise conditional solutions (default is true).
 • dropmultiplicity
 Do not return multiple identical solutions of polynomials (default is false).
 • explicit
 Express RootOfs in solution as radicals when possible (default is false).
 • maxsols = posint or pos_infinity
 Limit the number of solutions returned (default is $\mathrm{\infty }$).

Description

 • Programming level interface to the solve engine. It does a minimal amount of pre- and post-processing and returns a list of solutions of the form {var1 = expr1, var2 <= expr2, .. }.
