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)

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?
