How to displaying π instead of long decimal

if I have this simple matrix

x = [0:pi/30:pi/2]

How to print the elements with "π" Greek letter instead of long decimal .. Thank you

Print for what purpose? In the command window? On a figure axis? Only this particular vector?

[Mahome]

yes, print in command window

Have you considered using LaTEX

Latex is not usable in the command window.

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), ']']

Thank you, but I think there some way is more professional than this,

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

[Walter Roberson]

sym(x) might work, possibly.
