中文说明： % function X = TruncatedGaussian(sigma, range) % X = TruncatedGaussian(sigma, range, n) Generate a pseudo-random vector X of size n, X are drawn from the truncated Gaussian distribution in a RANGE braket; and satisfies std(X)=sigma. RANGE is of the form [left,right] defining the braket where X belongs. For
