MatrixPolynomialAlgebra[Coeff] - extract a coefficient of a matrix of polynomials
Calling Sequence
Coeff(A, x, n)
Coeff[row](A, x, vn)
Coeff[column](A, x, vn)
Parameters
A
-
Matrix
x
name; specify the variable in which the entries of A are rational polynomials over Q
n
integer
vn
list of integers
Description
The Coeff(A,x,n) command computes the n-th coefficient of a matrix of polynomials A.
The Coeff[row](A,x,vn) command computes the vn[i]-th coefficient of A for row i. That is, the number of elements in the list vn must equal the number of rows in A.
The Coeff[column](A,x,vn) command computes the vn[i]-th coefficient of A for column i. That is, the number of elements in the list vn must equal the number of columns in A.
