SETDATA Set data matrix in a data set B=SETDATA(A,DATA) B=SETDATA(A,DATA,FEATLAB) INPUT A SDDATA set DATA Data matrix (double) FEATLAB SDLAB object with feature labels corresponding to DATA OUTPUT B SDDATA object DESCRIPTION SETDATA sets the new data matrix DATA into data set A. This is useful when we compute a new representation of samples in A. Data set feature labels are preserved, if DATA has the same number of features (columns) as A and FEATLAB is not specified. New feature labels are generated ('Feature x') if FEATLAB is not provided and feature sizes differ. EXAMPLE >> load digits % load digit data set >> mean_data=mean(+a,2); % compute column vector with a mean of each sample % create data set b with a single 'mean' feature (from data set a) >> b=setdata(a,mean_data,sdlab('mean'));
