WebApr 12, 2024 · There are two possible approaches. First, you can use inverse transform sampling. If U is uniformly distributed in ( 0, 1), then. follows a Rayleigh distribution. You can recall that if F is a cumulative distribution function and X ∼ F, then F ( X) is uniformly distributed, so you can take U = F ( X) and using normally distributed X transform ... WebSep 15, 2024 · 0. Matlab's randn () function generates a vector of zero-mean normally distributed data. You can proove that if you mutliply a random variable by a constant, then you will mutliply its variance by the square of this constant. More generally : V a r [ a × x + b] = a 2 × V a r [ x] M e a n [ a × x + b] = a × M e a n [ x] + b.
