schubertCodim -- compute the codimension (i.e., height) of a Schubert determinantal ideal or ASM ideal



Given a partial alternating sign matrix or a permutation in 1-line notation, outputs the codimension of the corresponding alternating sign matrix ideal or Schubert determinantal ideal.

i1 : schubertCodim matrix{{0,0,0,1},{0,1,0,0},{1,-1,1,0},{0,1,0,0}}

o1 = 5
i2 : schubertCodim {1,3,2}

o2 = 1
