how to concatnate cells within a column

i have a column of cells that i would like to group/concatnate into one row for example:

Carboplatin & pemetrexed maintenance pemetrexed docetaxel

should become this: Carboplatin & pemetrexed||maintenance pemetrexed||Docetaxel

how do i do this without having to manually input the following code:

 a=strcat (data2.REGIMEN{1},'||',data2.REGIMEN{2},'||',data2.REGIMEN{3});

Can you provide a short example with expected result?

[andrew]

for example column contains{5,6,7,8,9,10,11,12,13,14...etc} and

outcome should be in one cell {5,6,7}, {8,9,10,11},

Answer 1

[dpb]

s=char(d.reg(1));
for i=2:length(d.reg)
  s=strcat(s,['||' char(d.reg(i))]);
end

Adding the "||" made trying to use comma list a pita in any way I could think of otomh, anyways...

Answer 2

[F.]

I think you should try this:

 % code
strcat( sprintf( '%s||', Data2 .REGIMEN{1:end-1} ) , Data2.REGIMEN{end} )

OR

 % code
Tmp = strcat(  Data2 .REGIMEN(1:end-1), '||' );
strcat( [ Tmp{:} ] , Data2.REGIMEN{end} )
