Implementing a complex function in Simulink

In Matlab's command window I obtained several equations which look like:

Tc1 = (- 2*J2*cos(t3)*sin(t1)*sin(t3)*n^2 + 2*J2*w3*sin(t3)*n)/cos(t2) - d2 + cos(t2)*(J2*cos(t3)*sin(t1)*sin(t3)*n^2 + J2*v3*sin(t1)) + J1*w1*w3 + J2*w1*w3 - J3*w1*w3 + J2*v2*cos(t1) + J2*n^2*cos(t1)*tan(t2) - J2*w2^2*cos(t1)*tan(t2) + 2*J2*w3^2*cos(t1)*tan(t2) + J2*w2^2*cos(t1)^3*tan(t2) - J2*w3^2*cos(t1)^3*tan(t2) - 2*J2*n*w2*cos(t3)*tan(t2) + 2*J2*w2*w3*sin(t1)*tan(t2) - J2*n^2*cos(t1)*cos(t3)^2*tan(t2) + 2*J2*n*w2*cos(t1)^2*cos(t3)*tan(t2) - 2*J2*w2*w3*cos(t1)^2*sin(t1)*tan(t2) - 2*J2*n*w3*cos(t1)*cos(t3)*sin(t1)*tan(t2)

In Simulink I use From and Goto blocks for all the parameters (Tc1, J1, J2, J3, t1, t2, t3 and so on).

Now I am wondering what the easiest way is to implement these long formulas in Simulink for a simulation. Normally I would just rebuild the equations using all kind of blocks in Simulink, but the equations I ended up with this time are much longer. Any ideas?

The only other alternative I can think of is to use the MATLAB Function block and write this out as a MATLAB function.

Thank you, that works fine!
