muEC::SFA::TosA – develops any symmetric function on the s-basis

The muEC::SFA::TosA function analyses sfa and develops any symmetric function in sfa on the basis of s-polynomials.

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

→ Examples

Call:

muEC::SFA::TosA(sfa, <alist>)

Parameters:

sfa: 

any valid expression of SFA

alist: 

a list of alphabets

Example 1:

muEC::SFA::TosA( h[4,3](2*A1) ); // BROKEN EXAMPLE

                 s[7](2 A1) + 3 s[5, 2](2 A1)

 

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

math

muEC::SFA::TosA( s[4]( p[4,3](2*A1) )^2 + q*p[2](A2),
