Assign all targets to training set
[trainInd,valInd,testInd] = dividetrain(Q,trainRatio,valRatio,testRatio)
[trainInd,valInd,testInd] = dividetrain(Q,trainRatio,valRatio,testRatio) assigns all targets to the training set and no targets to either the validation or test sets. It takes the following inputs,
Number of targets to divide up.
Training indices equal to 1:Q
Empty validation indices, 
Empty test indices, 
Here are the network properties that define which data division function to use, what its parameters are, and what aspects of targets are divided up, when train is called.
