Hi, i'm trying to plot a phase plane but it doesn't work :(
This is the matlab code:
clear all
clc
[X,Y] = meshgrid(0:0.2:5,0:0.2:5);
u = -((3*X)/(2+X))*(Y-X);
v = zeros(26);
figure
quiver(X,Y,u,v);
And matlab answer me: Warning: Matrix is singular to working precision.
Thank you very much for your help !!!

You need to do element-wise (array) operations.
Change the ‘u’ assignment to:
u = -((3*X)./(2+X)).*(Y-X);
and it works.
