MATLAB: APPEND TWO CELL ARRAY

cellcell arraycell arrays

HI I HAVE TWO ARRAY {AA}=<24X20> AND {AB}=<47X20>. iF I USE AC={AA;AB} MATLAB CREATE TWO CELL? HOW CAN I APPEND AB AFTER AA IN A SINGLE CELL ARRAY?

vertcat

AC = vertcat(AA,AB);

To fix what you have just don't use {}

AC = [AA;AB];

newcellarray = [cellarray2,cellarray1]

You can use unique:

>> C = {'aa', 'aa', 'ab' ,'ab', 'ab', 'ac', 'ac', 'ad'};
>> [~,~,idx] = unique(C)
idx =
   1   1   2   2   2   3   3   4
