How to generate random orthogonal codes in matlab

• currently i am using randi(0:1,5,16)
• which gives me 1 bit random values of 0 and 1
• but I want to generate two bits of 0 and 1 which is 00 10 11 00 10 10
• how should i generate such values.
• i tried (randi(0:1, 5, 16)+'0') but its giving me 49 48 49 48 values which i am not looking for I want values only with respect to 11 00 01 10 00 11
• Kindly help

What does this have to do with orthogonality? You did explicitly state orthogonal.

As for the problem of generating numbers like 00, MATLAB does not recognize the differeence between that and 0. You COULD convert them to character of course.

help char

but that would do nothing to generate anything orthogonal. So if you really want help, then you need to explain what you need.

mat2str(de2bi(randi([0,3],5,16)))
