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

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;

but if i have large dataset and many number of classes everytime shall i need to do like this. or is there any other suggestion
Y = zeros(3, 5);
Y(2,1:3) = 1;

yes,sir,if the class number is 3,then use one-hot type to range target data Y
