edit-merging the values

i have two matrices andf a code

AC=[HHH CLL]

   B=A2(:,1)

AC=[1 2 3 ;5 6 7 ;8 9 0]

B=[1 ;4 ;5]

   [tf, loc] = ismember(B, AC(:,1));
  outC = [reshape(B(tf),[],1), AC(loc(tf), :)]

this code works now,but,i i add some strings to

AC=[HHH  S CLL]

AC=[1 2  'A' 3 ;5 6 'B' 7 ;8 9 'C' 0]

this code generates error

Error using ==> cell.ismember at 28

Input must be cell arrays of strings.

Error in ==> main at 328
 [tf, loc] = ismember(B, AC(:,1));

PLEASE HELP

You cannot mix numeric values and characters in the same numeric array.

I do not have access to test at the moment, but I suspect that

AC=[1 2  'A' 3 ;5 6 'B' 7 ;8 9 'C' 0]

is constructing a character array, equivalent of

AC=[char(1) char(2) 'A' char(3); char(5) char(6) 'B' char(7); char(8) char(9) 'C' char(0)];

If I am correct, then you would be trying to ismember() against a character array, but character arrays are not permitted for ismember() -- only numeric arrays, or character strings (row vectors), or cell arrays of strings.

OK THANKS WALTER ,can u answer my another question plz

CLL_MEAN(:,:,1) =

83.0000 83.0000 0.6469

87.0000 87.0000 0.2616

;

;

;

;

CLL_MEAN(:,:,50) =

90.0000 90.0000 -0.1415

96.0000 96.0000 0.6981

i used

CLL_MEAN = [CLL_combinations(:,1:2,:) mean(CLL_combinations(:,3:end,:),2)]

can u tell how to display only the 2nd and 3rd column in

CLL_MEAN plz

[Walter Roberson]

c2 = CLL_MEAN(:,2,:); c3 = CLL_MEAN(:,3,:);

[c2(:), c3(:)]
