While using Neural network pattern recognition tool(nprtool) in matlab,(For classification after getting all features) first we have to give input data from the workspace as a database file and then it asks for target data defining the desired output. I can't understand that if,i give input the features_vector of an image,then from where can i get the target data_vector?I mean how to estimate the target_data for each feature..

If there are c classes or categories and N examples of I-dimensional inputs.
[ I N ] = size(input)
[ c N ] = size(target)
where the target matrix contains c-dimensional {0,1} unit vectors satisfying
sum(target) = ones(1,N)
vec2ind(target) = classindices
ind2vec(classindices) = target
Look at the target vectors of the classification data examples in
help nndatasets
doc nndatasets
Hope this helps.
Thank you for formally accepting my answer
