D.2.7.12 randomBinomial

Procedure from library random.lib (see random_lib).

Usage:
randomBinomial(k,u[,o,b]); k,u,o,b integers

Return:
binomial ideal, k homogeneous generators of degree d, u<=d<=o, with randomly chosen monomials and coefficients in the interval [-b,b] (default: u=o, b=10).

Example:
 
LIB "random.lib";
ring  r = 0,(x,y,z),lp;
ideal i = randomBinomial(4,5,6);
i;
==> i[1]=-x4z-xz4
==> i[2]=8x2y3+8xy3z
==> i[3]=-4x2y2z2-4xy5
==> i[4]=5x3yz2+5xz5
