Can some one explain me how this function works

if ((i == eq.n1) & (j == eq.n1) & (k == eq.n1))
switch varargin{3} % what is means ?
case 'x'
Aijk =
case 'y'
Aijk =
case 'z'
Aijk =
otherwise
error('unknown case');
end
else
error();
end

return

check the third input parameter, if x,y,or z, assign it to Aijk,
otherwise raise error

function Aijk = Prob(i, j, k, parameter, varargin)
if ((i == eq.n1) & (j == eq.n1) & (k == eq.n1))
switch varargin{3} % what is means ?
case 'x'
Aijk =
case 'y'
Aijk =
case 'z'
Aijk =
otherwise
error('unknown case');
end
else
error();
end

return
