MATLAB: How to change the settings for randstream in Matlab or Simulink

random number generator

I am using gaussian random generator using Simulink, which uses a randseed to generate the random numbers as noise based on mean and variance. How do I change the randstream settings in matlab or simulink, which is used for the generation of these random numbers? I believe the default setting is the Mersenne twister for the randstream…

MATLAB: How to use the Mersenne “Twister” algorithm to generate random numbers form the Uniform Random Number Block in Simulink

The ability to use the Mersenne "Twister" algorithm to generate random numbers from the Uniform Random Number block is not available in Simulink.

To work around the issue, try one of the following:

1. Use the RAND function in an Embedded MATLAB function with 'twister' as the method.

2. Use the RAND function in MATLAB to create the data and use the Inport or FromWorkspace block to bring this data into Simulink.
