I have a problem in the classification stage the classify function doesn't work. It needs more parameters although it work in the examples with two parameters only

XTrain = AllTrainCel(1:200000,:)'; 4 * 200000

YTrain = categorical([1 0 -1 -2]'); % 4 * 1;

layers = [ ...

sequenceInputLayer(200000)

%reluLayer

LSTMLayer

fullyConnectedLayer(4)

softmaxLayer

classificationLayer];

options = trainingOptions('sgdm');

net = trainNetwork(XTrain',YTrain',layers,options);

net = fitnet([10 10]);

XTest = AllTestCel(1:200000,:)';

YTest = categorical([1 0 -1 -2]');

[YPred] = classify(net,XTest); % gives me error here
