Hi, Just a quick question.
I generate a series of normally distributed random numbers with mean 1.5 and standard deviation 0.3.
d1 = 1.5 + 0.3.*randn(100,1)
Anyone know how I can exclude all the negative results?
Thanks a lot!

d1(d1 < 0) = [];
Note that the result will not be a normal distribution and will not have mean 1.5 or standard deviation 0.3 !
