3 Writing S-Functions As C-MEX files

mdlOutputs

Calculation of outputs. For our timestwo

S-function, mdlOutputs takes the input,

multiplies it by two, and writes the

answer to the output. This routine is

called du ring the simulation loop each

time t he output of

timestwo needs to be

updated. For the above block diagram, it

is called at every time step.

mdlTerminate

Perform tasks at end of simulation. The

timestwo S-function has no t ermination

tasks to perform; therefore, this routine is

empty.
