A general answer is Yes. But what function you are talking about - could you please mention here? MATLAB function block or MATLAB system, S-function or something else in Simulink environment?

A Simulink Function is like a Simulink model. Depending on the blocks that are used inside the Simulink Function, some blocks have initial value parameters, others don't.

You can use the "Initial Condition" block to set the initial condition of the signal at its input port.
