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 ).

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, .. }.
