Generating random variable from certain standard deviation and mean

Could you please help me how can I generate random variable from Gaussian distribution with zero mean and 0.3 standard deviation?

Bob - Note that the page you are sending them too is a question asking how to generate numbers that have a truncated normal distribution. That is different.

[Bob Thompson]

Fair point. The finer points of math are not my strong suit, so I was going based on the title.

Answer 1

[Andrei Bobrov]

a = .3;%  standard deviation
b = 0; %  mean
out = a.*randn + b;

Answer 2

[Torsten]

n = 100; 
x = 0.3*randn(n,1)

generates 100 normally distributed random numbers with mean 0 and standard deviation 0.3.

Thank you alot guys for the helpful comments!
