Hi eveybody
I could not fill the gap betwween 2 curves. it is shown in below figure.
can anyone help me?
thanks
The code I used is:
plot(KI1,KP1);
xlabel('K_I');
ylabel('K_P');
grid on
hold on
x2=zeros(1,150)
y=linspace(-20,40,numel(x2))
plot(x2,y,'linewidth',2)

KI1 and KP1 are vectors. they can have any value.

What do you mean by "fill the gap"? Do you want to connect the start and end points so that this becomes a closed curve? If so, this should do it:
plot([KI1(:); KI1(1)], [KP1(:); KP1(1)]);
xlabel('K_I');
ylabel('K_P');
grid on

Here is my shot
y = 0:0.1:pi;
x1 = -sin(y);
x2 = y*0-0.3;
[xc,yc] = polyxpoly(x1,y,x2,y);
xx = [xc(1) x1(x1<x2) xc(end)];
yy = [yc(1) y(x1<x2) yc(end)];
plot(x1,y,x2,y)
patch(xx,yy,'r')
line(xc,yc,'marker','o')
success?
