Hi All,
I am trying to classify sequence datasets using deep learning by applying
net = trainNetwork(XTraining,YTraining,layers,options);
K>> whos XTraining
Name Size Bytes Class Attributes
XTraining 6586x1 63910544 cell
K>> whos YTraining
Name Size Bytes Class Attributes
YTraining 6586x1 9598 categorical
but I am getting the following error
Error using trainNetwork (line 184)
Out of range subscript.
Caused by:
Error using sub2ind (line 43)
Out of range subscript.
I don't get why I get the out of range subscript error since XTraining & YTraining are both 6586x1.
However if I try
net = trainNetwork(XTraining(1:4000),YTraining(1:4000),layers,options);
it works well but not for any ranges above 4000 :|
Can someone please let me know what's going on and how I can solve this issue?

What would happen if one of the layers requested an array larger than the size stored in your cells, XTraining{1} and so on?
In particular if it fails for values above 4000 check that XTraining{4001} is the same size as XTraining{1}

@Vinay Kulkarni In my case, I had forgotten to change the number of layers in fullyConnectedLayer according to the number of classes. And there were some issues with the length of data in each cell, so I got to ensure that all data had the same size and length. Hope it helps.

Thanks @Susan.
I too had made mistake in number of classes. Once that corrected the training started.
