If you trained Mdl using a numeric matrix, then the predictor names in Mdl.PredictorNames and the corresponding predictor variable names in X must be the same. To specify predictor names during training, use the 'PredictorNames' name-value argument. All predictor variables in X must be numeric...
In this text we have given examples of very simple output and sometimes quite elaborate output. We now consider the input of text and data via the keyboard. An interactive way of obtaining input is to use the function input. One form of this function is >> variable = input('Enter data:...
