how can we perform element wise Logical OR operation ?

Question

how can we perform element wise Logical OR operation on two vectors of different size having binary values?

Answer 1

Here is a solution using functions from core MATLAB only (namely dec2bin and bin2dec):

a = 3;
b = 5;

bits = dec2bin(a,8)-'0' | dec2bin(b,8)-'0';
c = bin2dec(char(bits+'0'));

where c will be 7 as expected
