Pmat

Calling sequence

Parameters

• p11 ...: polynomials

Description
The Pmat data type matrix polynomial object. Each entry of the matrix is an (univariate) polynomial.

Operations on polynomial matrices

Herited methods

• A.redim[m,n] reshape matrix to size mxn. m or n can be set to -1
• A.concatr[B] A = [A,B]
• A.concatd[B] A = [A;B]
• A.perm_elem[p,q,dim] permute values, rows (dim=1) or columns (dim=2).

• If I and is J are respectively row and column indices A(I,J) is the submatrix of A with entries in I and j.
• A(I,:) is the submatrix of A with row indices in I.
• A(:,J) is the submatrix of A with comumn indices in I.
• A(:,:) is A
• A(:) is the column matrix obtained by stacking the columns of A.

• If I and is J are row and column indices A(I,J)=B inserts matrix B into matrix A in rows I and columns J.
• A(I,:)=[] removes the rows of A with indices in J.
• A(:,J)=[] removes the columns of A with indices in J.

• m2p : make a polynomial from its coefficient vector.
• pmat_create : polynomial matrix creation.
• length(A) returns the number of entries in A.
• size(A) returns in a 1 x 2 vector the dimensions (rows, columns) of A. size(A,1) (resp. size(A,2)) retuns the number of rows (resp. columns) of A.
