In my Simulink model, I have an Embedded MATLAB Function which generates random variables by rand command periodically during the simulation interval. Now, I want to run multiple simulations with parsim command. However, the same random variables are generated in different (multiple) runs of the model. I tried to add rng('shuffle') command into Embedded MATLAB Function, but it gave error saying it is not supported to use 'shuffle' command in Embedded MATLAB Function. Then, I tried to add rng(seed) command in Embedded MATLAB Function. rng(seed) works fine in Embedded MATLAB Function if the seed is a static number (but of course generates the same random variables since the seed integer is the same). However, if I try to change it in each run (by 'From Workspace' block), it again gives error complaining about this matrix value not having a time value etc.
Do you have an advice to have different random variable realizations in Embedded MATLAB Function block in each parsim loop?
Thanks in advance,
