M-file name trial
function varargout= trial (t, c, flag)
switch flag
case ''
varargout{1}=f(t,c);
case 'jpattern'
varargout{1} = jpattern(t,c);
case 'mass'
varargout{1} = mass(t,c);
otherwise
error(['Unknown flag ''' flag '''.']);
end
% ------------------------------------------------------------
function S = jpattern(t,c)
%code for jpattern
%---------------------------------------------------------------
function M = mass(t,c)
%code for mass
%---------------------------------------------------------------
function Gi=jacobianri(t,cp)
%code for jacobianri

while running at command prompt!!
options=odeset('OutputFcn','odeplot','OutputSel',[ind],'JPattern','on'
