%% Calculate Mean Values of Groups of Data % Calculate the mean heights by gender for groups of patients and display the results. % % Load patient heights and genders from the data file |patients.mat|. % Copyright 2015 The MathWorks, Inc. load patients whos Gender Height %% % Specify groups by gender with |findgroups|. G = findgroups(Gender); %% % Split |Height| into groups specified by |G|. Calculate the mean height by % gender. The first row of the output argument is the mean height of the female % patients, and the second row is the mean height of the male patients. splitapply(@mean,Height,G)
