I have a excel spreadsheet with 14 Columns and 1084 rows. I have to comapre the data in each row to eachother. Would it also be possible to do any of these and if so how would i do it.
Mdl = fitcdiscr(Tbl,ResponseVarName)
Mdl = fitcnb(Tbl,ResponseVarName)
Mdl = fitcknn(Tbl,ResponseVarName)
Mdl = fitctree(Tbl,ResponseVarName)
Im not sure how to go about doing this and i am very lost so any help is appreciated.

Generate table:
matrix = rand(1084,4); % making 4 columns because I don't feel like creating 14 column names
Tbl = array2table(matrix);
Tbl.Properties.VariableNames = {'Example','VariableName','Thisone','Anotherone'}
Tbl = 1084×4 table

Note, you could just read your table from the Excel spreadsheet directly using readtable function.
Chose Response Variable
ResponseVarName = 'Thisone';
Mdl = fitcknn(Tbl,ResponseVarName)
Mdl =
ClassificationKNN PredictorNames: {'Example' 'VariableName' 'Anotherone'} ResponseName: 'Thisone' CategoricalPredictors: [] ClassNames: [7.0290e-04 7.2041e-04 0.0015 0.0022 0.0039 0.0059 0.0063 0.0067 0.0074 0.0106 0.0112 0.0114 0.0123 0.0130 0.0155 0.0157 0.0169 0.0177 0.0183 0.0210 0.0212 0.0214 … ] ScoreTransform: 'none' NumObservations: 1084 Distance: 'euclidean' NumNeighbors: 1 Properties, Methods
