The method produces the rxr minors of a dxn matrix of indeterminates. Note that the variables in the output are indexed by strings.
gfan Documentation This program will generate the r*r minors of a d*n matrix of indeterminates.Options:-r value: Specify r.-d value: Specify d.-n value: Specify n.-M2: Use Macaulay2 conventions for order of variables.--names: Assign names to the minors.--dressian: Produce tropical defining the Dressian(3,n) instead. (The signs may not be correct, that is the equations may not be Pluecker relations.)--pluckersymmetries: Do nothing but produce symmetry generators for the Pluecker ideal.--symmetry: Produces a list of generators for the group of symmetries keeping the set of minors fixed. (Only without --names).--parametrize: Parametrize the set of d times n matrices of Barvinok rank less than or equal to r-1 by a list of tropical polynomials.
