Hi,

I have a cell matrix:

'56' 'mat find false' '89 mm' 'mat 96 kl'

I want to split:

'mat find false' --> 'mat' 'find false' (one cell to two cells)
'mat 96 kl' -->'mat' '96 kl'

desired Output:

'56' 'mat' 'find false' '89 mm' 'mat' '96 kl'

Many thanks in advance,

Or regexp-based: if

C = {'56', 'mat find false', '89 mm', 'mat 96 kl'} ;

then

 result = regexp(C, '(mat)?\s?(.*)', 'tokens', 'once') ;
 result = [result{:}] ;
 result(cellfun(@isempty, result)) = [] ;

outputs:

 result =
  1×6 cell array
    '56'    'mat'    'find false'    '89 mm'    'mat'    '96 kl'

As usual I mention that cellfun('isempty') is faster than cellfun(@isempty), because it does not call a Matlab function in a loop, but checks the emptiness inside the Mex function.

Thanks Jan!

I'll have to frame the following on my wall:

Easy to solve with looping through the list from the end:

for n=length(c):-1:1
    idx=strfind(c{n},' ');
    if ~isempty(idx)
        c((n+1):(end+1))=c(n:end);
        c{n}(idx(1):end)=[];
        c{n+1}(1:idx(1))=[];
    end
end
