What does randn do in MATLAB?
By default, randn(n,"like",1i) generates random numbers from the standard complex normal distribution. The real and imaginary parts are independent normally distributed random variables with mean 0 and variance 1/2 .
What is difference between Rand and randn in MATLAB?
Answers and Replies
Code: rand() Return a matrix with random elements uniformly distributed on the interval (0, 1). The arguments are handled the same as the arguments for `eye'. randn() Return a matrix with normally distributed pseudo-random elements having zero mean and variance one.
What is rng command in MATLAB?
rng( seed ) specifies the seed for the MATLAB® random number generator. For example, rng(1) initializes the Mersenne Twister generator using a seed of 1 . The rng function controls the global stream, which determines how the rand , randi , randn , and randperm functions produce a sequence of random numbers.
What does Rand stand for in MATLAB?
X = rand returns a random scalar drawn from the uniform distribution in the interval (0,1). example. X = rand( n ) returns an n -by- n matrix of uniformly distributed random numbers.
