Hello there, I would like to be able to compute smith normal forms for matrices with coefficients in some specific ring, to be choosen each time. I am not able to properly creat a matrix in $\mathbb{Z}[\sqrt{-1}]$. For instance . M=matrix([[2+I,0],[0,1]]) then M.change... A local Smith form algorithm (step 1) In this section, we show how to generalize the construction in Wilkening (2007) for finding a canonical system of Jordan chains for an analytic matrix function A(I») over C at I»0 = 0 to finding a local Smith form for a matrix polynomial A(I») with respect to an irreducible factor p(I») ofa?†(I») = det[A(I»)]. The new algorithm reduces to

**Smith Normal Form My thoughts/summaries**

In transforming an integer matrix into Smith or Hermite normal form using known techniques, the number of digits of intermediate numbers does not appear to be bounded by a polynomial in the length of the input data as was pointed out by... the code should be able to generate smith normal form of a matrix with two types of input matrices. one is the integer matrix(Z) and also for polynomial matrix(Z2). the output should be able to print left multiplication matrix, right multiplication and the smith form of matrix.

28/07/2009 · Smith normal form is a generalization of Gaussian elimination to matrices with coefficients coming from PID. This can be used, for example, in finding a -basis for the kernel/image of a matrix of integers, or proving the often-cited structure theorem for finitely generated module over PID.... The Smith normal form of a matrix is diagonal, and can be obtained from the original matrix by multiplying on the left and right by invertible square matrices. In particular, the integers are a PID, so one can always calculate the Smith normal form of an integer matrix. The Smith normal form is very useful for working with finitely generated modules over a PID, and in particular for deducing

The matrix D is known as the Smith normal form of the matrix A. Re- turning to our problem, for given matrices A and B of respective sizes m n and m p, let P, Q, and D be as in Theorem 1.... the diagonal matrix D is called the Smith normal form (SNF). The above form of the SNF of a matrix was described in the original paper of Smith [23] on this topic.

- I will assume you are referring to the Jordan normal form. The motivation comes from finding the eigenvalues and eigenvectors of matrices, which is a common task in physics and engineering problems.
- Smith normal form A: n?n matrix over commutative ring R (with 1) Suppose there exist P,Q ? GL(n,R) such that PAQ := B = diag(d 1,d 1d 2,...d 1d 2···dn), where di ? R. We then call B a Smith normal form (SNF) of A. NOTE. (1) Can extend to m?n. (2) unit·det(A) = det(B) = dn 1d n?1 2 ···dn. Thus SNF is a re?nement of det. Smith Normal Form and Combinatorics – p. 2.

- In this report we explore the Smith normal form for the incidence matrix between two adjacent ranks in Young's lattice, and for the product of this matrix with its transpose.
