Hi guys,
I'm new to Matlab and Neural Network.
Let's say i have 3 inputs and an output array.
I want to normalize each column individually. Can i use mapminmax? Does it normalize by row or by column?

1. There is no need to explicitly use mapminmax on NNET inputs or outputs. It is a default.
2. It works on the rows of a matrix. Therefore, all you have to do is transpose.
Hope this helps.
Thank you for formally accepting my answer
Greg
