MATLAB: How to compare pair of rows in a column and report it in hexadecimal format

comparehexadecimalmatrixrows

Hello,
I have a 512×1 matrix (512 rows and 1 column)
The value of ROW1 should be compared with ROW2, similarly ROW3 with ROW4, etc. I have to compute this 256-bit response and report it in hexadecimal format assuming; if ROW1 > ROW2 then 1 & if ROW2 > ROW1 then 0
In this way I will get 256×1 from this.
Please advise!

Try this:
x=reshape(mymatrix,2,[])';
y=num2str(x(:,1)>x(:,2))';
y=dec2hex(bin2dec(reshape(y(y~=' '),8,[])'))';
hexRep=y(:)';
