MATLAB: Problem in finding the mode for the following matrix

finding common elementsmode

Consider a matrix JJ
JJ
JJ =
    2.3159    1.9527    1.8476    1.9527
    2.7977    0.8633    0.0298    0.8633
    0.0438    1.0645    0.0438    0.0880
    0.7228    2.0592    0.7228    0.2329
    0.2228    1.4990    0.2228    0.0414
Now,I need find the mode in each row. I tried this already by giving the command mode(JJ,2). The answer I got is this.
mode(JJ,2)
ans =
    1.9527
    0.0298
    0.0438
    0.2329
    0.0414
As it can be seen the answer is wrong with respect to 2nd, 4th and 5th rows. The common elements or mode of 2nd, 4th and 5th is 0.8633, 0.7228 and 0.2228 respectively. Why the mode command is showing a wrong answer??
Any help is highly appreciated.

It works for me with the given atrix. Are you sure this is the exact values of JJ? Otherwise you need to truncate it to a tolerance. This is done as
 newMtx = round(1/tol*mtx)*tol;
truncation to 4 decimals would then be have tol = 1/10^4
 newMtx = round((10^4)*mtx)/10^4;
Thank you for accepting the answer :)
