Hi

I am trying to legend the roots of my function as zeta1,zeta2....

I used this answer,

figure();
x = real(r0);
y = imag(r0);
for ii = 1:numel(r0)
    plot(x(ii),y(ii),'ro');
    hold on
    % %     text(x(ii),y(ii),sprintf('Zero #%d',ii), ...
    text(x(ii),y(ii),sprintf('Zero %d',ii), ...
        'VerticalAlignment','top','HorizontalAlignment','center');
    grid on
end

I find this answer work but HOW can I write zeta instead of zero in this line text(x(ii),y(ii),sprintf('Zero #%d',ii), ...
