Random Numbers in Simulink
显示 更早的评论
Hi,
I would like to implement a particle filter in Simulink. Therefor it is necessary to get random numbers (up to 10000 per cycle) for sampling particles.
In Matlab you can find the randn(10000,1) function and everything works fine. Now I switched to Simulink. I use the embedded M Files, but I always receive failures when using randn in the Embedded M File. Simulink has a "Random number" block. Instead of a scalar you can input a vector ones(10000,1) as "mean" parameter. The output is a vector(10000,1) of one (always the same) random number.
Has anybody an idea how to get a vecotr of 10000 different random numbers in Simulink equivalent to the randn function in Matlab?
Thank you very much for you help.
Greetings.

Change the "Seed" property of the "Random number" block to 1:10000 so each series of random number is different.

Not sure if this is your intention. Do you want 10000 random numbers at once, or do you want one random number at a time, for 10000 time steps?
