mean = A/(A+B)
std = sqrt(A*B/((A+B+1)*(A+B)^2))
If mean and std are given, you can "invert" the formulae to get the A and B values for MATLAB's "betarnd".

You can calculate the parameters of the beta distribution from the mean and variance. The formula for doing this is on the Wikipedia page for the beta distribution. There is also a good description of the process here.
Once you have that, you can use the betarnd function.
