MATLAB: How to reshape (digitTrain4DArrayData) inbuilt number dataset provided in MATLAB

Question

digitTrain4DArrayData data set is having dimension of 28 * 28 * 1 * 5000 (5000 samples) . How can we reshape it into 784 * 5000, to train it using neural network pattern recognizer in matlab for ANN.

Answer 1

[XTrain,YTrain] = digitTrain4DArrayData;

Use the reshape function as follows:

reshapedXTrain = reshape(XTrain,784,5000);
