It looks like you have a cell array of strings. The single quotes only appear when the array displays; they are not part of the strings. Note how the display changes depending on how the cell is viewed:
C = {'A', 'Bee', 'Ce'} % We see the single quotes - cell array
C{:} % We don't.
If you want to change to a character array, the quotes will not display:
D = char(C)
But now things are not so easy to deal with... For example, look at:
size(D)

Like Matt says, they're not really there. You see them just as an artifact of how you displayed them. Use fprintf() if you want to display them in some custom way, like without quotes.
clc;
ca = {'A' 'B' 'C';...
'D' 'E' 'F';...
'G' 'H' 'I'}
for row = 1 : 3
fprintf('%c %c %c\n', ca{row,1}, ca{row,2}, ca{row,3});
end
In the command window:
ca =
'A' 'B' 'C'
'D' 'E' 'F'
'G' 'H' 'I'
A B C
D E F
G H I

A={' A ' 'B' 'C'
'D' 'E' 'F'
'G' 'H' 'I'}
B=strtrim(A)
out=sprintf('%c %c %c \n',char(B'));
disp(out)
