I am trying to use MATLAB to plot the direction field of a system of first-order ODEs. I can plot the direction field of one single ODE using quiver(), but I have no idea about how to do it with a system of ODEs. For exmple, I want to draw the direction field of the following system of ODEs:
Could anyone show me how to do this, or provide me with some reference links and websites of instruction so that I can self-study? Thank you so much!

Hi @Kieth Duong,
The basic code looks like the following:
[X, Y] = meshgrid(-2:4/14:2, -2:4/14:2);
U = 2*X + 9/5*Y;
V = -5/2*X - 1*Y;
quiver(X, Y, U, V)
axis square
xlabel('x_{1}'), ylabel('x_{2}')
