Specify columns inside a for loop

Hi
I would like to know if the code I attached will do the following: I want the value in the for loop to multiply by the price. But more specifically, I want this value to multiply by 10 if it is in the columns 1-8 and for the rest of the columns multiply by 15.
Thanks
for j=1:365
for i=1:25
if data(1,i)>=1 && data(1,i)<=8
price=10;
else
price=15;
end

You are only checking of the data within any given column is between 1 and 8, which isn't what you describe to be wanting.
Just compare i's:
if i >= 1 && i <= 8
%...
else
%...
end
I represents the columns you are iterating over, so you would want to test versus i.

You might not need to use a for loop
% rand data
data = rand(365,25);
% colums 1-8
data(:,1:8) = data(:,1:8)*10;
% colums 9 -25
data(:,9:25) = data(:,9:25)*15;
