Hello everyone,

Hope you are all in good health.

I have multiple matlab funcitons inside my simulink model and each of those matlab function blocks includes a rand() function for genrating random numbers.

My problem is that for the same timestep, all blocks output the same random number. The following timestep results in a random number different from the previous timestep but again the same for all blocks at this particular time step.

I need to generate different random number for each block at every time step in simulink. How can I achieve that ?

Thanks in advnace

Stay safe
