ElimHomogMat

matrix for elimination ordering

Syntax
ElimHomogMat(ElimInd: LIST, W: MAT): MAT

Description
This function returns a matrix for a term ordering eliminating the indeterminates with indices in ElimInd for inputs which are homogeneous wrt the weights in the matrix W . If you don't understand what this means, just use ElimMat ;-)

NOTE: This function used to be called HomogElimMat up to version 5.1.4, and had swapped arguments.

Example
/**/  ElimHomogMat([2,3], mat([[1,5,2]]));
matrix(ZZ,
 [[1, 5, 2],
  [0, 1, 1],
  [0, 0, -1]])
