you could use Jos' excellent FEX submssion allcomb:

>> a = [1,0,1;1,1,0;1,1,1];
>> b = [0,1;1,0];
>> cell2mat(allcomb(num2cell(a,2),num2cell(b,2)))
ans =
     1     0     1     0     1
     1     0     1     1     0
     1     1     0     0     1
     1     1     0     1     0
     1     1     1     0     1
     1     1     1     1     0

There is also the special case where the number rows are not multiples of each other:

>> [repmat(a,size(b,1),1),repmat(b,size(a,1),1)]
ans =
     1     0     1     0     1
     1     1     0     1     0
     1     1     1     0     1
     1     0     1     1     0
     1     1     0     0     1
     1     1     1     1     0

MATLAB: How can we create a vector of length n

There are many ways of doing this. E.g., use the ones( ) function and divide by 10. Or use the zeros( ) function and add 1/10. Or use the repelem( ) function. Etc.
