the file has three columns
*xvalues* *y values* *energy values*
4 5 344
5 1 285
0 0 455
0 1 203
the problem is i want to arrange 1st and 2nd columns as coordinates , so that (0,0) is followed by (0,1) and so on with there values ..
how can i sort it to align values such that the above chart is sorted to

sortrows(a)
Note: in your sample "a" here, your 4th row is [0 0 203] which does not appear in your desired output "b". Your desired output corresponds to your original data matrix.
