Hi,
You can use a ‘for’ loop to do the same.
Please refer to the following code to understand the problem:
z = [0 3 0; 1 2 3];
[n, m] = size(z);
for i = 1:n
for j = 1:m
if z(i,j) == 0
fprintf('\t')
else
fprintf('%d\t', z(i,j))
end
end
fprintf('\n')
end
This will produce the following output:
3
1 2 3

Ran in:
x = [0 3 0; 1 2 3];
c = sprintfc('%g', x.');
c(x.' == 0) = {''};
fprintf('\t%s\t%s\t%s\n', c{:})
3 1 2 3
% Or:
s = compose("%g", x);
s(s == "0") = "";
fprintf('\t%s\t%s\t%s\n', s.')
3 1 2 3
