Advances for state feedback multivariable using canonical form.

[varargout]=sym2cell(varargin)
```function [varargout]=sym2cell(varargin)
%SYM2CELL Sym matrix polynomial format to cell format.
%
% Syntax: [varargout]=sym2cell(varargin)
%
% Inputs :
%           n polynomial matrices.
%
% Outputs :
%           n cells.
%
% Example
% syms D P Q
% P(1,1)='D^2+2';P(1,2)=1;P(2,1)='D^3+D^2+D';P(2,2)='D+7';
% [P]=sym2cell(P)
%
% Other m-files required:
% Subfunctions: P1=c2s(P)
