I was wondering how to plot a straight line based on a loop I wrote. For a range of numbers,and a passed function, f, if the value of the number is greater than function, f, its supposed to draw a straight line f(a). The code is as follows:
for y=ymin:.1:ymax
if f(y) > 0
h1=yline(f(y), 'b.', 'MarkerSize', 4);
elseif f(y) < 0
h2=yline(f(y), 'r.', 'MarkerSize', 4);
end
for s=zeroSols(1):zeroSols(length(zeroSols))
h1=yline(f(s), 'k.', 'MarkerSize', 4);
end

From my understanding,
you want to plot a strainght line f(a) when a>f(a). This can achieved by adding the if condition.Similar if there are any other condition make use of elseif and else.
As an example
% let f is a function that takes input parameter
if a>f(a)
yline(f(a),'-r'); % draws a line at f(a) with red color
end
