Answer 1

[KSSV]

Let data be the column/row vector you want to normalize between -1 and 1.

clc; clear all ;
data = rand(100,1) ;  % a random data
normalized_data = -1 + 2.*(data - min(data))./(max(data) - min(data));

Answer 2

%dataSet = your data
min_L = -1;
max_L = 1;
dataSet = dataSet/norm(dataSet, Inf); %Normalize between 0 and 1
dataSet = (dataSet*(max_L - min_L)) + min_L; %Normalize between min_L and max_L
