Code Explaination (For Loop)

 function [y]=f6(x)
 global data 
 x=abs(x); 
n=length(data(:,1));
for i=1:n-1
    if x(i)>1;
        x(i)=1;
    else
    end
    P(i)=data(i+1,4)+x(i)*(data(i+1,5)-data(i+1,4));
end

Can anyone explain the for loop please?

My data is a 3x5 matrix & i'll use it for genetic algorithm.

The code is doing linear interpolation between column 4 and column 5, using abs(x) as the portion of the way between the columns.
