hello,
I have a problem in matlab function block, where I use the trigonometric function, conversion function (ex:degtorad..) ... when I simulates a first part it works, but once I pass execter:
x = degtorad (var);
s = cos (x) * 2
... that it generated this error :
Expected Either a logical, char, int, fi, single, double gold. Found a MATLAB type. MATLAB kinds are returned from calls to the MATLAB interpreter and are not supported inside expressions. They May only be used on the right-hand side of assignments and have arguments to MATLAB calls.
can u help me?

thank's for your reply,
it solves some but for:
f = cos (var) * sin (var) * cos (arg) + sin (var) * cos (arg);
I proceed in the same manner: vc = cos (var) .. then F1=vc*vs*ca;.. and f = F1 + F2;
but it generates mismatch Size!!

Your var and your arg are not the same size and your arg is not scalar.
You need to define what size of output you want for that case.
Code would help.
