Plot system difference equations
Is this way correct to plot system of difference equation. For example
StreamPlot[{(.2 (x^2) - x*y - .01 (y^2)), -.1 (y^2) + .9 x*
y + .02 (x^2)}, {x, -5, 5}, {y, -5, 5}, Axes -> True,

plot discrete system by mathematica
if I have a discrete system x(n+1)= 0+y , y(n+1)= -0.5x +0
The fixed point (0,0) is center by Jacobian., I do not know how Plot this by using Mathematica code to get center. I am thankful if any one …

Solve 2D Difference Equations
If I have a system of difference equations
$$
\begin{cases}
x(n + 1) = x(n) + x(n) y(n) + y(n)^2 \\
y(n + 1) = y(n) - x(n)^2 + y(n)^2
\end{cases},
\text{ with }
\begin{cases}
x(0) = 1\\
y(0) = 2
\end{ …

Plot 2-D system difference equations
If I have 2-D system difference equations
x(n+1)=x(n)-5y(n) ,
y(n+1)= 2x(n)+y(n)
I need to plot this system. I did :
StreamPlot[{x - 5 y , …
