This option allows to compute the multiplicities in case the ideal I is not prime. In fact the output of gfan does not include them and hence they are computed separately by this package. By default the ideal is assumed to be prime.
i1 : QQ[x,y,z]; |
i2 : I=ideal(x^2-y^2); o2 : Ideal of QQ[x, y, z] |
i3 : isPrime I o3 = false |
i4 : T=tropicalVariety(I,Prime=>false,ComputeMultiplicities=>true); |
i5 : rays T o5 = 0 3 o5 : Matrix ZZ <--- 0 |
i6 : maxCones T o6 = {{}} o6 : List |
i7 : multiplicities T o7 = {2} o7 : List |
The object ComputeMultiplicities is a symbol.
