What would be the input data matrix and target data matrix in MATLAB Neural Network Pattern Recognition toolbox?

I am new to Neural Networks and have no prior experience of AI,ML or deep learning. Please help me out. I have data sets of 10 different kind of hand-motions(Gestures) from M1 to M10. Each hand-motion is recorded via 12 different electrodes. Every motion, from every electrode has 156504x1 size in Matlab. I need to know that how to arrange my data for input data matrix and target data matrix.

No. Of motions=10 No. Of Electrodes=12 Size of each Signal= 156502X1 double

After training network it should tell that from which motion a signal belongs?
