You mean like this:
% Start string with x= and a left bracket.
asciiPi = 112
str = sprintf('x = [');
% Add the 16 elements.
for k = 0 : 15
str = sprintf('%s%d*%c/30, ', str, k, 960);
end
% Get rid of trailing slash and add right bracket.
str = [str(1:end-2), ']']

Not really. MATLAB is a computational tool. Pi is just a number. Why worry about how it is displayed? About as much as you will do is this:
sym(pi)
ans =
pi
