this equation
and this code
xn = zeros(size(p))
mx=max (p(2));
mn=min (p(1));
mmd=mx-mn;
for i=1:(P,1)
xn(i,:)=(p(i,:)-mn)./(mmd)*(mx-mn)+mn
end
p is data for normalization
I applied min and max equation that is mention above.
When I applied the code the output wrong, please can you tell where the wrong in the code

I found the proper equation for max and min normalization
- The previous one the normalization is default between [o,1]. But, in this we select and values as mention in equation *(mx-mn)+mn

Is the previous question solved relative to what you asked there? If so then you should Accept one of the solutions. But if what you were wanting was just to correct the question, then you should have edited that one instead of starting a new question.

Hi Abudlla,
It appears the mistake is in:
(mx-mn)+mn
this line should be (new_max_a-new_min_a)+new_min_a and in your code it is: (max_a+min_a)+min_a.
In other words you are lacking variables for new_max_a and new_min_a.

Dear this variable we can write new _max and new_min or min and max
I am asking the code dosn't display the output properly
