function result = normltrand(mu,sigma2,left)
%NORMLTRAND  compute random draws from a left-truncated normal
%            distribution, with mean = mu, variance = sigma2
% ------------------------------------------------------
% USAGE: y = normltrand(mu,sigma2,left)
% where:   mu = mean (scalar or vector)
%      sigma2 = variance (scalar or vector)
%        left = left truncation point (scalar or vector)
% ------------------------------------------------------
% RETURNS: y = (scalar or vector) the size of mu, sigma2
% ------------------------------------------------------
% NOTES: This is merely a convenience function that
%        calls normtrand with the appropriate arguments
