Compute descriptive statistics from sample data, including measures of central tendency,
dispersion, shape, correlation, and covariance. Tabulate and cross-tabulate
data, and compute summary statistics for grouped data. If your data contains
NaN) values, MATLAB® arithmetic operation functions return
However, specialized functions available in Statistics and Machine Learning Toolbox™ ignore these missing values and return a numerical value
calculated using the remaining values. For more information, see Data with Missing Values.
