MATLAB: Merge row and column headers into column header or Get Index Names

Question

Hi

This might be an easy qn sorry. So for simple example i have two headers. One 4×1 row header and one 1×4 column header as such

          monkey   rabbit   tiger   snail 
 
  monkey          
 
  rabbit          
 
  tiger          
 
  snail         
  

What i want to achieve is 16 combination with the word vs in the middle. This will be the final column header. So output will be:

  monkey vs monkey   monkey vs rabbit   monkey vs tiger   monkey vs snail   rabbit vs monkey ............ snail vs tiger   snail vs snail 
      

Is there a way to quickly get the names of an index ie monkey vs monkey =1,1 snail vs snail 16 x 16. Thank you for any help.

col = {'monkey', 'rabbit', 'tiger', 'snail'};
row = {'monkey', 'rabbit', 'tiger', 'snail'}';

Answer 1

col = {'monkey', 'rabbit', 'tiger', 'snail'};
row = {'monkey', 'rabbit', 'tiger', 'snail'};  % can differ from col
Result = cell(numel(col), numel(row));
for c = 1:numel(col)
    for r = 1:numel(r)
        Result{c, r} = [col{c}, ' vs ', row{r}];
    end
end

Or without a loop:

nCol   = numel(col);
nRow   = numel(row);
Result = strcat(repmat(col(:), 1, nRow), {' vs '}, repmat(row, nCol, 1));
