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:
