## `SFA::ToeA` -- develops any symmetric function on the `e`-basis

#### Call(s)

`SFA::ToeA(sfa <,alist>)`

#### Parameters

`sfa` | - | any valid expression of `SFA`
`alist` | - | a list of alphabets

#### Introduction

The `SFA::ToeA` function analyses `sfa` and develops any symmetric function in `sfa` on the basis of `e`-polynomials.

One can develop only symmetric functions of which alphabets are given in the optional argument.

#### Example 1

    >> muEC::SFA::ToeA( s[3,1](2*A1) );

                  e[4](2 A1) - 2 e[3, 1](2 A1) + e[2, 1, 1](2 A1)

    >> muEC::SFA::ToeA( s[3,1](2*A1)*m[2,1](A2^2), [ A2^2, A3 ] );

                                             2             2
                    s[3, 1](2 A1) (e[2, 1](A2 ) - 3 e[3](A2 ))

    >> muEC::SFA::ToeA( s[2]( p[4,3](2*A1) ) + q*m[2,1](A2^2),
             [ p[4,3](2*A1) ] );

                                                                      2
           e[1, 1](p[4, 3](2 A1)) - e[2](p[4, 3](2 A1)) + q m[2, 1](A2 )
