correlated_valuesandcorrelated_values_norm. Make the code easier to follow. Also use the more efficient Cholesky decomposition in cases where the user-provided covariance matrix is positive-definite. If it is strictly positive semi-definite then use the eigenvalue decomposition that was previously used.Note, previously
correlated_values_norm(which accepts a normalized correlation matrix) did the numerical lifting andcorrelated_values(which accepts a covariance matrix) calledcorrelated_values_norm. This is reversed now. Nowcorrelated_valuesdoes the numerical work andcorrelated_values_normcallscorrelated_values.
