%% Split Table Data Variables and Apply Function % Calculate the mean body-mass-index (BMI) from tables of patient data. Group % the patients by gender and status as smokers or nonsmokers. % % Load patient data and grouping variables into tables. % Copyright 2015 The MathWorks, Inc. load patients DT = table(Height,Weight); GT = table(Gender,Smoker); %% % Define a function that calculates mean BMI from the weights and heights of % groups or patients. meanBMIFcn = @(h,w)mean((w ./ (h.^2)) * 703); %% % Create a table that contains the mean BMI for each group. [G,results] = findgroups(GT); meanBMI = splitapply(meanBMIFcn,DT,G); results.meanBMI = meanBMI
