these are the two arrays i have
fri =
1 2 3
j =
0 1 2 3 4 5 6
i want to divide each element inside fri by one value of j at once. ex : 1/0,2/0,3/0 after that 1/1,2/1/3/1 and so on.
when i perform Xij = j./fri it gives an error that matrix sizes must be equal.(logically this is wrong as i see). is there any way to perform this operation and get values? any help will be highly appreciated.

>> fri = 1:3;
>> j = 0:6;
>> bsxfun(@rdivide,j(:),fri)
ans =
0.00000 0.00000 0.00000
1.00000 0.50000 0.33333
2.00000 1.00000 0.66667
3.00000 1.50000 1.00000
4.00000 2.00000 1.33333
5.00000 2.50000 1.66667
6.00000 3.00000 2.00000

fri = 1:3
j = 0:6
j = j'

result  = j./fri
