I have a population generated by pop=[pop;x;y;z;cst,fr]; where first 4 rows are x, second 3 rows are y and third 8 rows are z. cst is sum of column 1 and fr is calculated failure rate of column 2.

            6        0.876
            5         0.99
            3        0.939

How can I sort the specific (16,32,48) rows followed by unchanged (1:15,17:31,33:47)? for example:
