multiple files

Hi i have a question how to multiple this two

a=[10 11 15 18 20 40 50 66 88]
b=[10^1,10^2,10^3,10^4]

so that the answer is for example 10, 100 1000 10000 how can i write a code for the above thanks

I suspect you want bsxfun() . Try

bsxfun(@times, a.', b)

Feels non-ideal. Any better solution?

>> C=A(:,1)+B(:,1)';
D=A(:,2)+B(:,2)';
reshape([C(:),D(:)],[],2)
ans =
   -1.0000   -1.0000
  -60.4000    1.2000
    5.6000  -20.8000
  -40.6000    7.8000
 -100.0000   10.0000
  -34.0000  -12.0000
    3.4000  -80.2000
  -56.0000  -78.0000
   10.0000 -100.0000

better one

>> m=size(A,1);
ind1=repmat(1:m,1,m);
ind2=repelem(1:m,m);
A(ind1,:)+B(ind2,:)
ans =
   -1.0000   -1.0000
  -60.4000    1.2000
    5.6000  -20.8000
  -40.6000    7.8000
 -100.0000   10.0000
  -34.0000  -12.0000
    3.4000  -80.2000
  -56.0000  -78.0000
   10.0000 -100.0000

This should work to create your vector of indices:

idx = bsxfun(@times, [1:10]', logspace(0,3,4));
idx = unique(fix(idx(:)));
idx =
           1
           2
           3
           4
           5
           6
           7
           8
           9
          10
          20
          30
          40
          50
          60
          70
          80
          90
         100
         200
         300
         400
         500
         600
         700
         800
         900
        1000
        2000
        3000
        4000
        5000
        6000
        7000
        8000
        9000
       10000

You could do this in one line, but there is no advantage to that, and it makes the code more difficult to read.
