shar = [1 2 3;
1 3 4;
1 4 5];
REP = repmat('v',3,1);
sharcell = num2cell(shar);
REPcell = cellstr(REP);
sharcell(:,1) = REPcell;

There are a couple of obstacles... In your examplex, the 'v' inside 'REP' is not a string (AKA character array). MATLAB expects a variable called 'v' and looks for its content. And even if REP would be a character array, you couldn't mix it with the DOUBLE valueas from 'shar'.
Depending on you appliation, you might use characters only, or a cell array.
