If you want to change the mean, just "translate" the distribution, i.e., add your mean value to each generated number. Similarly, if you want to change the variance, just "scale" the distribution, i.e., multiply all your numbers by sqrt(v). For example,

WebMean of the normal distribution, specified as a scalar value or an array of scalar values. To generate random numbers from multiple distributions, specify mu and sigma using arrays. If both mu and sigma are arrays, then the array sizes must be the same. If either mu or sigma is a scalar, then normrnd expands the scalar argument into a constant array of the same … Webwhere x and μ are 1-by-d vectors and Σ is a d-by-d symmetric, positive definite matrix. Only mvnrnd allows positive semi-definite Σ matrices, which can be singular. The pdf cannot have the same form when Σ is singular..

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 ...
