MATLAB normalized code

method 1: 

nMax = max(data3); nMin = min(data3);data3 = (data3 - nMin)/(nMax - nMin);
方法2：

MappedData = mapminmax(OriginalData, 0, 1);

Method 3:

The first step to obtain the maximum and minimum; second portion obtains a normalized value

function [y]=guiyiha_gan(x)
max=0;min=0;
y=[];
for i=1;length(x)
     if x(i)>max
         max=x(i);
     end
     if x(i)<min
         min=x(i);
     end 
end
for i=1:length(x)
    y(i)=(x(i)-min)/(max-min);
end

end
