Thus, - vec_mx (v *m powers_mx A d) = horner_mx A (rVpoly v). - char_poly A == the characteristic polynomial of A. - char_poly_mx A == a matrix whose determinant is char_poly A. - companionmx p == a matrix whose char_poly is p - mxminpoly A == the minimal polynomial of A, i.e., the smallest monic - polynomial that annihilates A (A must be nontrivial). - degree_mxminpoly A == the (positive) degree of mxminpoly A. - mx_inv_horner A == the inverse of horner_mx A for polynomials of degree - smaller than degree_mxminpoly A. - integralOver RtoK u <-> u is in the integral closure of the image of R - under RtoK : R -> K, i.e. u is a root of the image of a - monic polynomial in R. - algebraicOver FtoE u <-> u : E is algebraic over E; it is a root of the - image of a nonzero polynomial under FtoE; as F must be a - fieldType, this is equivalent to integralOver FtoE u. - integralRange RtoK <-> the integral closure of the image of R contains - all of K (:= forall u, integralOver RtoK u). - This toolkit for building formal matrix expressions is packaged in the - MatrixFormula submodule, and comprises the following: - eval_mx e == GRing.eval lifted to matrices (:= map_mx (GRing.eval e)). - mx_term A == GRing.Const lifted to matrices. - mulmx_term A B == the formal product of two matrices of terms. - mxrank_form m A == a GRing.formula asserting that the interpretation of - the term matrix A has rank m. - submx_form A B == a GRing.formula asserting that the row space of the - interpretation of the term matrix A is included in the - row space of the interpretation of B. - seq_of_rV v == the seq corresponding to a row vector. - row_env e == the flattening of a tensored environment e : seq 'rV_d. - row_var F d k == the term vector of width d such that for e : seq 'rV[F]_d - we have eval e 'X_k = eval_mx (row_env e) (row_var d k). -</div> -<div class="code"> -
