Why use softmax as opposed to standard normalization?

"Normalize" values to sum 1 but keeping their weights

WebN = normalize(___,"center",centertype,"scale",scaletype) uses the "center" and "scale" methods at the same time. These are the only methods you can use together. If you do not specify centertype or scaletype, then normalize uses the default method type for that method (centering to have a mean of 0 and scaling by the standard deviation).
