Getting error using Linear Discriminant Analysis(LDA) in MATLAB.

I am trying to classify training and testing data using LDA classify in MATLAB R2018b and getting error.

Error : Error using classify

TRAINING must have more observations than the number of groups.

I have following matrics for training and testing.

feature_training= 1440 x 9

class_training= 1440 x 1

feature_testing= 1152 x 9

class_testing= 1152 x 1

Note: I already have more Training Elements than Testing Elements.

[error_training,error_testing,classification_training,classification_testing]...
    = ldaclassify(feature_training,feature_testing,class_training,class_testing);

Where ldaclassify, is below function.

function [TrainErr,TestErr,TrainPredict,TestPredict] = ldaclassify(TrainData,TestData,TrainClass,TestClass)

TrainPredict = classify(TrainData,TrainData,TrainClass);
TestPredict = classify(TestData,TrainData,TrainClass);

TrainErr = sum(TrainPredict ~= TrainClass)/length(TrainClass)*100;
TestErr = sum(TestPredict ~= TestClass)/length(TestClass)*100;
end

Can you upload the data in a MAT file, so that we can actually run your code?

Here are the files, I am using for classification
