other matrix has the value

REP=[v

   v

   v]

i want to replace the first row of shar using REP

I tried this code shar(:,1) = REP(:,1); it gets replaced as 118 instead of string 'v'.Help me Thanks in advance

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.
