I create a vector field of a equation system, also I want to represent the spefic solution of the system in that field but I think that I do it wrong.
this is the system:
dx/dt=P-ay
dy/dt=Q-bx
the code:
x1=-1;
x2=5;
y1=-1;
y2=5;
N = 20;
x = linspace(x1,x2,N);
y = linspace(y1,y2,N);
[X,Y]= meshgrid(x,y);
U1 = P - a.*Y;
V1 = Q - b.*X;
quiver (app.Axes2,X,Y,U1,V1);
xlim(app.Axes2,[0 5])
ylim(app.Axes2,[0 5])
hold (app.Axes2,'on')
yh = (P/a)./100;
xh1 = -10;
xh2 = 40;
plot (app.Axes2,[xh1,xh2],[yh,yh]);
hold (app.Axes2,'on')
yv1 = -10;
yv2 = 40;
xv = (Q/b)./100;
plot (app.Axes2,[xv,xv],[yv1,yv2])
hold (app.Axes2, 'on')
s = Q.*x-(b.*x.^2)/2-P.*y+(a.*y.^2)/2;
plot (app.Axes2,x,s,'r')
hold (app.Axes2,'off')
and the axes:
I think that the code is correct but it doesn't have any sense the axes for me, someone could help me?

Hi,
From my understanding you are manually trying to solve the equation. The following documentation should help you solve the system of differential equations in an efficient way.
