Simulink: Continuos time, time-invariant operations

Hi,

I want to do pretty trivial stuff in Simulink but don't know how to deal
with it:

- Continuous time operation, if possible variable step solvers

- A signal should come from MATLAB workspace and be sampled (that's just
"From Workspace")

- The simulation time is divided into M periods (M ~ 1000) and in each
period, the signal should be multiplied by a different sinusoid

- This signal is fed into different, continuous time transfer functions

- At the end of each period (e.g., given as timestamps) the current
value of the continuous signal should be saved (sampled) and exported to
MATLAB

So I would need either a (continuous time) sine source where the
frequency can be changed over time. Or some way to create 1000
sinusoidal blocks (without copy&pasting them) and MUXing the correct
source at each time.

Any ideas how to implement this?


Thanks
Peter
