Could anyone help me how to solve the following issue

i am having the matrixA= [3.1110 3.5665 3.5816 3.6923 4.2398 4.3484 4.3399 4.3447;

0.7787 0.5452 0.6372 0.5718 0.2473 0.2016 0.2089 0.2229;

0.1319 0.1788 0.2026 0.1927 0.1307 0.1767 0.1960 0.1825;

0.0859 0.0676 0.0646 0.1232 0.0858 0.1020 0.1103 0.1339]

in this matrix i want to select three maximum values from each column.

i tried with the command max(A) where it gives only one maximum value from each column.

Could anyone help me how to select more than one maximum value from each column.

maxk(A,3,1)

i am using 2015a matlab version.

I think maxk cannot be performed on that version.

a =

    3.1110    3.5665    3.5816    3.6923    4.2398    4.3484    4.3399    4.3447
    0.7787    0.5452    0.6372    0.5718    0.2473    0.2016    0.2089    0.2229
    0.1319    0.1788    0.2026    0.1927    0.1307    0.1767    0.1960    0.1825
    0.0859    0.0676    0.0646    0.1232    0.0858    0.1020    0.1103    0.1339

>> max(a')

ans =

    4.3484    0.7787    0.2026    0.1339

i want to select two maximum values from each column

hence the result is

a=[3.1110 3.5665 3.5816 3.6923 4.2398 4.3484 4.3399 4.3447;

0.7787 0.5452 0.6372 0.5718 0.2473 0.2016 0.2089 0.2229]
