Purpose
Min-Max scaling
Synopsis
- [xcorr,mins,maxs] = minmax(x,options); %perform min-max scaling
Description
Scales rows (or columns) of the input x to be have a minima of 0 and a maxima of 1.
Inputs
- x = M by N matrix of data to be scaled (class "double" or "dataset").
Optional Inputs
- options = Options structure. See details below.
options = a structure array with the following fields:
- mode: [ 1 ] dimension of data on which to calculate the minima and maxima for scaling. 1 = over rows (to scale variables); 2 = over columns (to scale samples). Default is 1.
Outputs
- xcorr = the scaled data (xcorr will be the same class as x)
- mins = vector of minima for each row (or column)
- maxs = vector of maxima for each row (or column)
