error in using predict function

predeictlabels = predict(classifier,testfeatures,'columns');

error in using this line in code

error is as

Error using internal.stats.parseArgs (line 42)
Wrong number of arguments.

Error in classreg.learning.internal.orientX (line 6)
    internal.stats.parseArgs({'observationsin'},{'rows'},varargin{:});

Error in classreg.learning.classif.CompactClassificationECOC/predict (line 323)
            [X,varargin] = classreg.learning.internal.orientX(...

Error in kite (line 62)
predeictlabels = predict(classifier,testfeatures,'columns'); % prdict level

The function predict takes only SVMModel & X as the input arguments. In your above code the 3rd argument 'columns' is causing the error, remove it.

predeictlabels = predict(classifier,testfeatures); % prdict level

Refer to documentation of predict for more information.
