Document Summary

Datafun: the help topic in which statistical functions are located. [maxval, maxind] = max(dataset): returns the maximum value of the dataset, as well as the first index it appears at. [minval, minind] = min(dataset): returns the minimum value of the dataset, as well as the first index it appears at. Mean(dataset): finds the average of the dataset. Mean(dataset, 2): finds the mean of each row of a matrix. Outliers can be removed by using the min and max functions. Harmmean(dataset): finds the harmonic mean of a dataset. Trimmean(dataset, n): trims the data values by n%, then finds mean. Mode(dataset): finds most common value ; if multiple are found, the smallest value will be returned. Union(v1, v2): returns all the values of the input arguments, sorted, without repeating values intersect(v1, v12): returns the values shared by both vectors. Setdiff(v1, v2): returns all values of v1 that are not found in v2.
