whats this code all about?

hiddenLayerSize = 70;
net = patternnet(hiddenLayerSize);
net.trainFcn = 'traingdx';  
net.trainParam.epochs = 100;
net.performFcn = 'mse';  % Mean squared error
net.divideParam.trainRatio = 100/100;
net.divideParam.valRatio = 0/100;
net.divideParam.testRatio = 0/100;

It is a PATTERNNET classifier. However, H = 70 without validation data sounds fishy. Can't tell unless input and target matrix sizes are given.
