MATLAB: Array indices must be positive integers or logical values!

Question

I have trained a regression model and now want to use it and get this error "Array indices must be positive integers or logical values". Here is the code

[RPMpred]=PredictRPM1sec(Tab_Pred_RPM(:,1:5));

and hereis my input array to the model

suggestions?

Thanks

‘suggestions?’

For one, post more of your code so the line you posted has a context.

I suspect that ‘PredictRPM1sec’ is an array, not a function, and if your ‘input array’ is what you posted in the image, those will be interpreted as subscript references. Note that none of them are integers, and some of them are negative.
