how to draw a directional field for this equation?
3 views (last 30 days)
I am trying to plot directional field for these differential eq.s
a) y’= 0.1y-sin(y)
b) y’ = y^2-3*y+1
c) y’ = -y(y-2)(y-4)/10
I was trying to write it like this, but then I am not sure how to give x.
[x, y] = meshgrid(-2:0.2:3, -1:0.2:2);
s = 1 - x.*y.^2;
% for slope function
% f = 1 - x y^2
quiver(x,y, ones(size(s)),s), axis tight
