function Pt = transpose(P)

% TRANSPOSE -- real transpose of matrix polynomial
%
%        Pt = transpose(P)
%        Pt = P.'

% This routine is not meant to be called by the user. It is called by
% Matlab when the expression P.' is encountered. It takes the real
% transpose of all the coefficient matrices.

Pt = P;
[n1,n2,n3] = size(P.coef);
% the next line just creates space for Pt of the correct size and data type
Pt.coef = reshape(Pt.coef,n2,n1,n3);
for i = 1:n3
    Pt.coef(:,:,i) = P.coef(:,:,i).';
