Plotting an image of a discrete dynamical system

Use the sliders to modify matrix entries. Click and drag locators (small disks) to modify initial points; ALT+Click to add/remove locators.

An alternative implementation using Graphics:

Manipulate[Legended[Graphics[{AbsolutePointSize[10], ColorData[97]@#, 
    Arrowheads[.03], Point @ pt[[#]], 
    Arrow[Partition[NestList[{{a, b}, {c, d}}.# &, pt[[#]], t - 1], 2, 1]]} & /@ 
     Range[Length[pt]], 
   ImageSize -> 400, Frame -> True, Axes -> True, 
   PlotRange -> 5 {{-1, 1}, {-1, 1}}], 
  Placed[LineLegend[ColorData[97] /@ Range[Length @ pt], Defer /@ pt, 
    LegendLabel -> "{x0,y0}", LegendFunction -> Panel], Right]],
 Spacer[10], Spacer[10], Spacer[10], 
 Grid[{{Item[Labeled[Control @ {{a, .8, Style["a", 18]}, 0, 1, Slider, 
        ImageSize -> Small}, Style[Dynamic[a], 20], Top], 
     Background -> (Dynamic @ ColorData[{"Rainbow", {-1, 1}}][a])], 
    Item[Labeled[Control @ {{b, .0, Style["b", 18]}, -1, 1, Slider, 
         ImageSize -> Small}, Style[Dynamic[b], 20], Top], 
       Background -> (Dynamic @ ColorData[{"Rainbow", {-1, 1}}][b])]},
    {Item[Labeled[Control @ {{c, .0, Style["c", 18]}, -1, 1, Slider,

Update: Modification of the second method for the example in OP's update:

ClearAll[a, b, aA, x0] aA[a_, b_] := {{2 a b - a - b, a b - a - b}, {2 (a + b - a b), 2 ( a + b) - a b}} x0 = {1, 1/3};

Manipulate[Graphics[{AbsolutePointSize[10], ColorData[97]@1, Arrowheads[.03], 
   Point@x0, 
   Arrow[Partition[NestList[aA[a, b].# &, x0, t - 1], 2, 1]]}, 
  AspectRatio -> 1, ImageSize -> 400, Frame -> True, Axes -> True, 
  PlotRange -> All], Spacer[10], Spacer[10], Spacer[10], 
 Grid[{{Item[Labeled[Control@{{a, 1, Style["a", 18]}, -1, 1, Slider, 
        ImageSize -> Small}, Style[Dynamic[a], 20], Top], 
     Background -> (Dynamic@ColorData[{"Rainbow", {-1, 1}}][a])], 
    Item[Labeled[Control@{{b, .5, Style["b", 18]}, -1, 1, Slider, 
        ImageSize -> Small}, Style[Dynamic[b], 20], Top], 
     Background -> (Dynamic@ColorData[{"Rainbow", {-1, 1}}][b])]}}, 
  Alignment -> {Center, Center}, ItemSize -> {16, 16}, Dividers -> All], 
 Spacer[10], 
 {{t, 1}, 1, 15, 1, Animator, AnimationRunning -> False, DisplayAllSteps -> True}, 
 Alignment -> Center, ControlPlacement -> Left]

If you want to control the starting point with a Locator:

Manipulate[Labeled[Graphics[{AbsolutePointSize[10], ColorData[97]@#, 
      Arrowheads[.03], Point@pt[[#]], 
      Arrow[Partition[NestList[aA[a, b].# &, pt[[#]], t - 1], 2, 1]]} & /@ 
        Range[Length[pt]], ImageSize -> 400, Frame -> True, 
   Axes -> True, PlotRange -> All, AspectRatio -> 1], 
  Dynamic[pt[[1]]], Top], Spacer[10], Spacer[10], Spacer[10], 
 Grid[{{Item[Labeled[Control@{{a, 1, Style["a", 18]}, 0, 1, Slider, 
        ImageSize -> Small}, Style[Dynamic[a], 20], Top], 
     Background -> (Dynamic@ColorData[{"Rainbow", {-1, 1}}][a])], 
    Item[Labeled[Control@{{b, .5, Style["b", 18]}, -1, 1, Slider, 
        ImageSize -> Small}, Style[Dynamic[b], 20], Top], 
     Background -> (Dynamic@ColorData[{"Rainbow", {-1, 1}}][b])]}}, 
  Alignment -> {Center, Center}, ItemSize -> {16, 16}, Dividers -> All], 
  {{pt, {x0}}, Locator, Appearance -> None,  LocatorAutoCreate -> False}, 
 Spacer[10], 
 {{t, 1}, 1, 15, 1, Animator, AnimationRunning -> False, DisplayAllSteps -> True}, 
  Alignment -> Center, ControlPlacement -> Left]

Edit

We can change x0 by Locator and change {a,b} by Slide2D.

A[{a_, b_}] := {{2*b*a - a - b, b*a - a - b}, {2 (a + b - a*b), 
    2 (a + b) - a*b}};
Manipulate[
 ListPlot[NestList[A[ab] . # &, x0, 15], Joined -> True, 
  PlotRange -> {{-10, 10}, {-10, 10}}, 
  AspectRatio -> 1], {{ab, {1, 1/2}, 
   Dynamic["{a,b}=" <> 
     ToString[ab, TraditionalForm]]}, {.8, .4}, {1.2, .6}}, 
 Dynamic["x0=" <> ToString[x0, TraditionalForm]], {{x0, {2, 1/3}}, 
  Locator}, ControlPlacement -> Right]

Original

A = {{Cos[π/3], -Sin[π/3] - .1}, {Sin[π/3], Cos[π/3]}};
x0 = {1, 1};
pts = NestList[A . # &, x0, 15];
ListPlot[pts, Joined -> True, AspectRatio -> Automatic]

enter image description here

Or

A = {{Cos[π/3], -Sin[π/3] - .1}, {Sin[π/3], Cos[π/3]}};
x0 = {1, 1};
pts = NestList[A . # &, x0, 15];
Graphics[Arrow[Partition[pts, 2, 1]]]
