For some reason the command "radical(I);" does not work for the polynomials with complex coefficients but works when the coefficients are rational. Can anything be done about it? |

radical does not work over "inexact" fields (like complex or real) because no factorization over such fields is implemented. Use the algebraic extension of Q by i with i2+1=0 (ring r=(0,i),....; minpoly=i^2+1;) |
