I made a model of Logistic Regression which has 4 inputs and 2 outputs '0' and '1'. I am having trouble in exporting the model to predict new data. my input is
T={67.753 67.395 67.122 67.938}
yfit = trainedModel.predictFcn(T)
and Output
exporting_model
T =
1×4 cell array
[67.7530] [67.3950] [67.1220] [67.9380]
Function 'subsindex' is not defined for values of class 'cell'.
Error in mlearnapp.internal.model.DatasetSpecification>@(t)t(:,predictorNames) (line 163)
extractPredictorsFromTableFcn = @(t) t(:,predictorNames);
Error in mlearnapp.internal.model.DatasetSpecification>@(x)extractPredictorsFromTableFcn(splitMatricesInTableFcn(x))
(line 164)
predictorExtractionFcn = @(x) extractPredictorsFromTableFcn(splitMatricesInTableFcn(x));
Error in mlearnapp.internal.model.DatasetSpecification>@(x)exportableModel.predictFcn(predictorExtractionFcn(x)) (line
167)
newExportableModel.predictFcn = @(x) exportableModel.predictFcn(predictorExtractionFcn(x));
Error in exporting_model (line 2)
yfit = trainedModel.predictFcn(T)
Please help me with it

No I tried it before. It is not working either. Can you give me some commands which I can use to predict new data with the model that I have exported.
