dec2gc.m

The function dec2gc converts a real positive numeric column vector to its gray code equivalent with a specified level of precision.

Example:
real_num = [34;78;123;7];%set of real numbers to be converted
N = 7;%precision level for gray coding
gray_code = dec2gc(real_num,N);

Result:
gray_code =

0 1 1 0 0 1 1
1 1 0 1 0 0 1
1 0 0 0 1 1 0
0 0 0 0 1 0 0

NOTE: N should be carefully chosen such that 2^N > max(dec)
