It is better to preprocess the input data before using 'fitcsvm'.

There is option to standardise your input data by setting the 'Standardize' flag to 'true'. It will center and scale each predictor variable by the corresponding weighted column mean and standard deviation. Standardization makes predictors insensitive to the scales on which they are measured.
