D.5.8.5 is_isProcedure from library
Example: LIB "sing.lib"; int p = printlevel; printlevel = 1; ring r = 32003,(x,y,z),ds; ideal i = x2y,x4+y5+z6,yx2+xz2+zy7; is_is(i); → // dim of singular locus = 0 → // isolated singularity if last number is 0 in dim-sequence: → 2,1,0 poly f = xy+yz; is_is(f); → // dim of singular locus = 1 → // isolated singularity if last number is 0 in dim-sequence: → 1 printlevel = p; |
