For loop not working
显示 更早的评论
I have a 2x4 matrix called A. I would like to find the sum of each column and divide each element in that column with the sum of that column. However, when I run the loop, the first 3 columns have no values in them. How do I rectify this? The following is my code:
A = rand(2,4)
for i=length(A)
B(:,i) = A(:,i)./sum(A(:,1));
end

A = rand(2,4)
for i=1:length(A) % using a single value
B(:,i) = A(:,i)./sum(A(:,i)); % divide each element with sum of that column
end
B
It seems you are using a single value in loop counter

if you want values for first 3 columns and rows, start with 1. you also need to update
sum(A(:,1)) % this is for 1st col only
with
sum(A(:,i) % corresponding column
