D.8.2.7 lex_solve

Procedure from library solve.lib (see solve_lib).

Usage:
lex_solve( i[,p] ); i=ideal, p=integer,
p>0: gives precision of complex numbers in decimal digits (default: p=30).

Assume:
i is a reduced lexicographical Groebner bases of a zero-dimensional ideal, sorted by increasing leading terms.

Return:
ring R with the same number of variables but with complex coefficients (and precision p). R comes with a list rlist of numbers, in which the complex roots of i are stored.

Example:
