Question regarding the "randi" and "rand" functions in MATLAB

I have a question regarding the randi function in the MATLAB which is a PRBS generator.

I wanted to know which polynomial degree is being implemented in MATLAB for "randi" and "rand" functions.

I wanted to know which PRBSx is used. Where, x is the integer.

Question asked based on Reference to following Wikipedia link: https://en.wikipedia.org/wiki/Pseudorandom_binary_sequence

Thanks.

That technique is not used unless specifically requested. See https://www.mathworks.com/help/matlab/math/creating-and-controlling-a-random-number-stream.html#brvku_2

Hello Walter,

Thank you for your response.

I need a PRBS23 random sequence generator to generate a array of random number.

Can you please suggest me the function in MATLAB which can accomplish this task.

Also, can you walk me through an example?

Thank you.
