load('Vepdata3.mat');
hLen=length(h);
figure;
plot(EEGdata); %plot EEGdata
xlabel('time(s)');
ylabel('Amplitude(microA)');
hold on;
threshold=40;
thresholdLine=40; % Draw a horizontal line at y = 40;
plot(thresholdLine,'r-');
title('thresholdLine');
xlabel('time(s)');
ylabel('Amplitude(microA)');

Try yline
yline(threshold, 'Color', 'r', 'LineWidth', 2);
instead of what you have
thresholdLine=40; % Draw a horizontal line at y = 40;
plot(thresholdLine,'r-');
