Actually,my equation is like:

M*dy = f(y).

Although M is nonsingular, but the inv(M) is very complicated, and
when put to the right side,it turns out to be abnormal output of some
of the states stay zero. So I have to use the Mass option in the

And f(y) is so complicated a nonlinear equation that I can't draw it
out in Simulink using small nonlinear blocks.So I have to use the s-
function block.

So where to add the options in s-funtion block in Simulink? I looked
up the docs of s-function but it seems that there is no guidance there
for such a case, then how can I do? Is there anyway to convert the
equation to another form?

Thanks in advance!
