Thanks John. My actual problem is this: my physical parameter is meaningless for negative values, however, from literature, the distribution of this parameter is Gaussian distribution.

Here is a function generating truncated Gaussin with correct standard deviation:

Obviously this distribution is "popular" enough to be documented in Wikipedia.

I add few modifications to make the function more stable:

Thanks for your entire replay, I get the new term 'truncated Gaussian distribution', and excellent code to implement them.

I am confused by one term: a truncated normal distribution with a mean 0.075 and standard deviation 1. The (0.075, 1) may be of two cases:
