How to normalize a single row wise in MACONT, or multiply equation to single column only

I am making a code for MACONT and using 3 normalization technique, I am unable to normalization single column with their respective value (0-1) eventually ended up normalizing the the whole data from 0-1

Or is this possible to mulitpy a certain equation to one coloumn only without extracting it

Hi Mrityanjay Kumar,

I understand that you want to normalize a single column or mulitply a certain equation to one coloumn only without extracting it.

Below are sample scripts to perform required opereations:

1. Normalize single column:

% Specify the column to normalize
colIndex = 2;
% Extract the column
col = data(:, colIndex);
% Normalize the column to the range [0, 1]
normalized_col = (col - min(col)) / (max(col) - min(col));
% Replace the original column with the normalized column
data(:, colIndex) = normalized_col;

2. Mulitply a certain equation to one coloumn only without extracting it:

% Specify the column to modify
colIndex = 2;
% Apply the equation directly to the column
data(:, colIndex) = data(:, colIndex) * 2;

This examples should give an idea of how to proceed and achieve the required task.

Hope this helps!
