how to display pi symbol instead of numerical value in the out of the given code
clc; clear all; close all;
nA=3.3;nB=2.25;
% nB=3.3;nA=2.25;
S=sign(1-(nA^2/nB^2));
x=-1i*log(S);
if x>0
disp('Zak Phase of 0th band = ')
disp(pi)
else
disp('Zak Phase of 0th band = ')
disp('0')
end
Zak Phase of 0th band =
3.1416

You can either use the symbolic math toolbox or print the symbol via the unicode value -
nA=3.3;nB=2.25;
% nB=3.3;nA=2.25;
S=sign(1-(nA^2/nB^2));
x=-1i*log(S);
if x>0
disp('Zak Phase of 0th band = ')
%pi as a symbolic number
disp(sym(pi))
%print the symbol via unicode value
fprintf('%c', 960)
else
disp('Zak Phase of 0th band = ')
disp('0')
end
Zak Phase of 0th band =
π
π

You can display pi as a sybolic
disp(sym(pi))
π
Or you can use a π-character (𝜋 or π).
disp("𝜋")
𝜋
disp("π")
π

How about this?
S = sprintf('Zak Phase of 0th band = %c',960);
disp(S);
Zak Phase of 0th band = π
