So I'm graphing the following (note: I'm also graphing a direction field) and when I plot it the graph stops when x=10. Any suggestions?
fishfun = @(y) (1.2*y.^2)/1+y.^2; y=linspace(0,10,200); %(1.2*y.^2)./(1+y.^2); %we generated TWO vectors 1.2y^2 and 1+y^2. To get
%the quotient, we need to divide COMPONENT WISE.
plot(y,(.65*y)-(0.65*y.^2/10.5)); title('Graph of Rainbow Trout') ylabel('Amount of fish (hundreds)') xlabel('Time (days)') hold on f= @ (t,y) (.65*y)-(0.65*y.^2/10.5)-(((1.2*(y^2))/(1+(y^2)))); dirfield(f,0:1:30, 0:.05:2) title 'Direction Field of Rainbow Trout'
