pi_siy_s.m

FISMAT accommodates different arithmetic operators, fuzzification and defuzzification algorithm, imp

function [ret,x0,str]=pi_siy_s(t,x,u,flag);
%PI_SIY_S	is the M-file description of the SIMULINK system named PI_SIY_S.
%	The block-diagram can be displayed by typing: PI_SIY_S.
%
%	SYS=PI_SIY_S(T,X,U,FLAG) returns depending on FLAG certain
%	system values given time point, T, current state vector, X,
%	and input vector, U.
%	FLAG is used to indicate the type of output to be returned in SYS.
%
%	Setting FLAG=1 causes PI_SIY_S to return state derivatives, FLAG=2
%	discrete states, FLAG=3 system outputs and FLAG=4 next sample
%	time. For more information and other options see SFUNC.
%
%	Calling PI_SIY_S with a FLAG of zero:
%	[SIZES]=PI_SIY_S([],[],[],0),  returns a vector, SIZES, which
%	contains the sizes of the state vector and other parameters.
%		SIZES(1) number of states
%		SIZES(2) number of discrete states
%		SIZES(3) number of outputs
%		SIZES(4) number of inputs.
%	For the definition of other parameters in SIZES, see SFUNC.
%	See also, TRIM, LINMOD, LINSIM, EULER, RK23, RK45, ADAMS, GEAR.

% Note: This M-file is only used for saving graphical information;
%       after the model is loaded into memory an internal model
%       representation is used.
