control parameters of a simulink block

Hi,
Is it possible to control parameters of a simulink block with another block? Say create a block which controls the 'seed' value of 'Random Number Generator'.
Thanks Senmeis

In general, this is not a supported workflow, please see How Do I Change a Block Parameter Based on the Output of Another Block? The suggested solution would be re-implement the block so that the parameter value is accepted via an input port.

You can do this by utilizing a MATLAB function that can call the set_param command. You may be able to use the interpreted MATLAB function which would be similar but I never tested it for set_param.
However, you cannot change the seed of the random number generator during simulation as it is not tunable during simulation.

Owen: I see. Your question threw me off: "Is it possible to control parameters of a simulink block with another block?" - suggests that you want to control parameters based on the output of another block.
If you simply need to control parameters before running the model, please follow TAB's suggestion.
