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), ...
