% a function to realize addition in field GF(2^5) % input 'a','b' are two decimal numbers range from 0 to 31 corresponding to numbers of GF(2^5) % output 'y' is a decimal number range from 0 to 31 corresponding to a number of GF(2^5) function y=rs_add(a,b) a1=de2bi(a,5); b1=de2bi(b,5); y1=a1+b1; y2=mod(y1,2); y=bi2de(y2);
