for example
A = {['a' 'b' 'c'] ['d' 'm' 'f'] ['j' 'k' 'l'] [1 2 3] [3 4 7] [1 4 2]}

for example
based on the first column
but I want to be flexible for example if I want to sort them from the second column, I would like to be able to do that

A =
'abc' 'dmf' 'jkl' [1x3 double] [1x3 double] [1x3 double]
'pqr' 'abc' 'jkl' [1x3 double] [1x3 double] [1x3 double]
If you want to sort based on first column use
sortrows(A,1) % sort the entire row based on column1
sortrows(A,2) % sort the entire row based on column2 and so on..

Check the function called sortrows(matrix, column). It might be helpful for what you want to do.
