how to create this target data? can I write manually like you mentioned? my input is 76*6 (76 images with 6 features) and I have 3 classes. means my target data should be 76*3. how to create this data.?
I have assigned labels to my database like "traindatabase.Labels" which gives 76*1 categorical data

yes，sir，may be the data should be one-hot type，such as
>> [x,t] = simpleclass_dataset;
>> nprtool
then，you will found that the t is
of course，if you want to make your own data，such as
X = rand(4, 5);
Y = zeros(3, 5);
Y(2,1:3) = 1;
Y(1,4:5) = 1;
