Plotting complicated function with asymptotes

45 views (last 30 days)
Hi,
I am struggling to plot this equation in Matlab
I have tried using plot, fplot and ezplot but none seem to be able to handle it. Would anyone be able to help me with this?

Did you try
y = linspace(7, 12, 1000);
signal = exp(y .* cot(y)) .* sin(y);
plot(y, signal, 'b-', 'LineWidth', 2);
grid on;
xlabel('y');
ylabel('Signal');

y = linspace(0, 16, 2000);
signal = exp(y .* cot(y)) .* sin(y);
% Get rid of vertical "asymptotes" by setting anything outside our viewing range to nan.
nanIndexes = signal > 100;
signal(nanIndexes) = nan;
% Plot signal in solid black line.
plot(y, signal, 'k-', 'LineWidth', 2);
grid on;
xlabel('N', 'FontSize', fontSize);
ylabel('y', 'FontSize', fontSize);
ylim([-10, 40]);
title('signal = exp(y .* cot(y)) .* sin(y)', 'FontSize', fontSize);
% Plot dashed line from (0, 0) to (7.5, 40);
hold on;
plot([0, 7.5], [0, 40], 'k--', 'LineWidth', 2);
% Plot dashed line from (0, 0) to (16, 15);
plot([0, 16], [0, 15], 'k--', 'LineWidth', 2);
% Make a black line along the x axis
yline(0, 'LineWidth', 2);
If that solves it, could you please "Accept this answer"? Thanks in advance.
