MATLAB: Creating a repeated matrix

matrix manipulation

HI all,
 I have the following code
k1=repmat({'S1'}, [3,1]) ;
k2=repmat({'S2'}, [3,1]) ;
 k3=repmat({'S3'}, [3,1])   ;
k4=repmat({'S4'}, [3,1])   ;
   k5=repmat({'S5'}, [3,1])   ;
    k6=repmat({'S6'}, [3,1])   ;
 ktotal= [k1; k2;k3;k4;k5;k6];
Is it possible to create "ktotal" with a more clever way? Probably with a loop?
thank you in advance

This is a more "clever" way:
   ixs    = repmat( [1:6], [3,1] );
   ktotal = arrayfun( @(ii) sprintf('S%u',ii), ixs(:), 'uni', false );
However, a for-loop is probably the "best" way:
    ktotal = cell( 6*3, 1 );
    for ii = 1:6
        ix = 3*(ii-1)+1;
        ktotal( ix : ix+2 ) = {sprintf('S%u',ii)};
    end
