Dear sir/madam,
I need to generate a uniform random variable with mean 0, and variance 10 for my project. How could I generate this in matlab? Looking forward to hearing from you soon.
Thanking you, BSD

((2*rand)-1)*sqrt(12/4)*sqrt(10)
The ((2*rand)-1) gives you a random variable with zero mean and a variance of 4/12. The rest scales it to a variance of 10.

Below expression will generate 1000 random numbers of any mean and standard deviation. And SD = sqrt(var)
y = standard_deviation.*randn(1000,1) + mean

The line of code you've written is fine for solving a question about generating random numbers, but it will not solve the original question.
Part of that original question, with some emphasis added, was "I need to generate a uniform random variable". The randn function generates normally distributed pseudorandom numbers.
