Hi,

I'm new to MatLab/Simulink an came upon something I could not find the answer. When I use the Simulink Mask posibility I have the "Initialization" code in the Mask Editor. In this code I would like to use the "Inherited" sampletime or samplerate from an input signal.

How can I get this sampletime or samplerate from the input signal in the Initialization code of the Mask.

best regards, Peter

Have you tried:

get_param(gcb,'CompiledSampleTime')

Thanks for the fast reply.

I tried your solution and it worked.

I have however a question about this solution.

The returned time is the "Simulation" sample time of the block. I'm not sure but is there also a Sampletime related to one of the imputs and how can I get that Sampletime.

This would also be needed if therewhere inputs with different sample rates (I think).

I think the sample time is computed at the block level, see:

I'm not sure you can have multiple inputs to a block with different sample times. A good practice would be to use a rate transition block to ensure all inputs to a block have the same sample time.
