double scythe::dnorm ( double  x, double  mean, double  sd  ) [inline] The normal density function. Computes the value of the normal probability density function with given mean and standard deviation sd, at the desired quantile x. It is also possible to call this function with a Matrix of doubles as its first argument. In this case the function will return a Matrix of doubles of the same dimension as x, containing the result of evaluating this function at each value in x, given the remaining fixed parameters. By default, the returned Matrix will be concrete and have the same matrix_order as x, but you may invoke a generalized version of the function with an explicit template call. Parameters: x The desired quantile. mean The mean of the distribution. sd The positive standard deviation of the distribution.
