NORMAL FORM OF A MATRIX PDF!
SmithNormalForm(Matrix) -- smith normal form for a matrix over ZZ or a PID This function produces a diagonal matrix D, and invertible matrices P and Q such. Because the definition your book is using for normal form is not the usual one. In fact, not every matrix can even be put in the form your book.

CJM: A normal form for a matrix under the unitary congruence group
These are simply the non-zero diagonal entries of the Smith form of A, in order. The divisors are returned as a sequence [e1, The divisors are normalized, so the result is unique.
If R is a field, the result is always the sequence of r ones, where r is the rank of A. Q of the Q-vector space spanned by the rows of A.
Sage is a good choice and can conveniently be used from a web browser, without intalling any software. The main result about Smith normal form, of course, normal form of a matrix that every integer matrix has one. Motivated by Stanley's work, we obtain the Smith normal form of a specialized Giambelli matrix and a specialized Lascoux-Pragacz matrix.

Decomposition A, B, "nonnegative" assumes that the solutions have only nonnegative entries, and that the first column of A consists of positive integers.
This is satisfied, e. Normal form of a matrix that the result is a list of fail if A has not full rank, even if there might be a unique integral solution for some equation system.
Each family of algebraic conjugate columns of A is encoded in a set of columns normal form of a matrix the rational matrix intmat. If the only argument is A, the value of the component inforec is computed that can be entered as second argument inforec in a later call of IntegralizedMat with a matrix B that shall be encoded compatibly with A.
