How do I save my answers with 2 for loops.

So I have a transfer function x= 1/(w+4m). m goes from 1 to 5 and w goes from 1 to 3. The first for loop is m and w is the loop inside. So basically I need to save my answer as the following array

x =[m1w1 m1w2 m1w3 m2w1 m2w2 m2w3 m3w1 m3w2 m3w3 m4......till m5w3]

the answer would be

x =[1/5 1/6 1/7 1/9 1/10 1/11.........1/23]

right now I have

 y = zeros(1,15);

 for m = 1:5

    for w= 1:3
    x = 1/((w+m*4));
    y(m) = x;

    end

 end

I know it's wrong.. how do i fix it? Thank you.

Using bsxfun is faster and neater than using loops:

>> X = bsxfun(@(m,w)1./(w+4*m), 1:5, (1:3).');
>> X(:)
ans =
          0.2
      0.16667
      0.14286
      0.11111
          0.1
     0.090909
     0.076923
     0.071429
     0.066667
     0.058824
     0.055556
     0.052632
     0.047619
     0.045455
     0.043478

can I make it horizontal...like 0.2 0.1111 0.1.... Thanks

[Stephen23]

Just use the normal tranpose operator: X(:).'

thx!

y(m,w) = x;

thanks, i tried this an hour ago, it works for my purpose as well. I just had to add

t=reshape(y',1,15) it converts it into horizontal array.
