Error using .' Transpose on ND array is not defined. Use PERMUTE instead.

I have this code but it give to me this error, how I can fix it?

 % Pass CNN image features to trained classifier
predictedLabels = predict(classifier, testFeatures);   _this is the code I want to compile_

[X,varargin] = orientX(X,expectedObsInRows,varargin)

 %   Copyright 2015 The MathWorks, Inc.

 [obsIn,~,varargin] = ...
    internal.stats.parseArgs({'observationsin'},{'rows'},varargin{:});
obsIn = validatestring(obsIn,{'rows' 'columns'},...
    'classreg.learning.internal.orientX','ObservationsIn');
obsInRows = strcmp(obsIn,'rows');

 if expectedObsInRows~=obsInRows
    X = X.';    _at this line I have the error mentioned_
end

 end

Thank you so much

Your testFeatures needs to be 2D, not 3D.

Be careful if you are working with images: RGB images are 3D.

How I can change my input? With rgbtogray? But my input to convent must be 227by227by3, maybe I have to change only testFeatures?

I also receive same error. I check my X is 4D. How i will know which row-columns i need to rearrange using premute?

did you get the solution to this problem @Paola Perrone?
