and i want to print it with nonthing where the zeros are and tabs beetween the numbers

i calld he matrix z

fprintf('%d\t%d\t%d\n',z(1,1:end))
fprintf('%d\t%d\t%d\n',z(2,1:end))

To check: the output should be

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

x = [0 3 0;  1 2 3];
c = sprintfc('%g', x.');
c(x.' == 0) = {''};

fprintf('\t%s\t%s\t%s\n', c{:})

	1	2	3

% Or:
s = compose("%g", x);
s(s == "0") = "";
fprintf('\t%s\t%s\t%s\n', s.')

		3	
	1	2	3
