Modifier and Type	Method	Description
static double	errOnSum(Matrix approx, Matrix exact)	Calculate mean error on sum for queue length metrics Returns mean absolute error relative to sum of each column Similar to MATLAB: mean(abs(exact-approx))/sum(exact)
static List<Integer>	getNonDelayStationIndices(Network model)	Get indices of non-delay stations
static double	mape(Matrix approx, Matrix exact)	Calculate Mean Absolute Percentage Error (MAPE) Wrapper for Utils.mape for benchmark compatibility
static double	maxErrorOnSum(Matrix approx, Matrix exact)	Calculate maximum error on sum for queue length metrics Returns max absolute error relative to sum of each column Similar to MATLAB: max(abs(exact-approx))/sum(exact)
static Matrix	randGallery(int rows, int cols, int seed)	Generate random gallery matrix (similar to MATLAB's randgallery) This creates a random matrix with values in [0,1]
