egr = Tier' % egr returns 'T2' 'S2' as 1*2 CELL
sgr = char(egr); % sgr returns T2
S2 as 2*2 char
My desired output should look like 'T2' 'S2' or 'T2','S2' in char

Note that the only way a 2x1 cell array can be converted into a 1x2 char array is if each cell of the array contain a single character, or one cell contains 2 characters and the other none.

egr = {'T2' 'S2'};
sgr = ['''', strjoin(egr, ''' '''), ''''];
disp(sgr)
This will display as
'T2' 'S2'
which is to say that sgr will be a character vector that contains those literal characters, which appears to be what you are asking for.
However, this appears to have nothing to do with your switch statement, since you have
switch (T3)
and T3 has nothing to do with egr or sgr.

yup, I made a mistake while i was posting it here, i was changing variables to avoid confusion, it is Switch(Sgr)

Note that in your switch,
case {'T2' 'S2'}
would match if Sgr is either 'T2' or 'S2', not if it is the character vector "'T2' 'S2'" .
If you are trying to indicate by case {'T2' 'S2'} that the condition should match if the input contained either 'T2' or 'S2' then you should probably be using any(ismember()) or similar.
Yeah, just now noticed that issue, thank you @ Walter Roberson

Tier={'T2';'S2'}'
egr=Tier
c=char(egr)

please read my question again, because c={'2';'4'} will return 2*1 cell array i.e {'2'}{'4'} and char (C) will return 2*1 char array '2' '1'

It's really not clear what you want. I would have thought that madhan's answer was what you asked for.
Please give a full example of an input and the desired output, using valid matlab syntax (as madhan did).

egr= Tier'
sgr= char(egr)
if(strcmp(view,'new')==1)
switch (T3)
case {'T2' 'S2'}
Tier='T2 (SII)';
case{'T3' 'S3' 'B3' 'C3' 'H3' '3D'}
Tier='T3 (SIIIA)';
case{'I4' 'R4' 'ID'}
Tier='IT4 (SIIIB)';
case{'F4' 'S4' 'C4' 'H4' '4D'}
Tier='FT4 (SIV)';
case{'C5' 'S5' 'H5'}
Tier='FT4 (SV)';
otherwise
Tier='';
end
end
% As sgr is returning T2 S2 as 2*2 Array(vertically), so when it is passed in to switch condition, it is not meeting any of the switch cases.
desired functionality is to stop at first case, I hope i was clear this time.
