我有一个矩阵,即一个非粗糙的列表列表,并给出一个坐标列表,例如以{{0,0},{1,1},{2,2},...{5,5}}
的形式,我想跟踪该矩阵中的路径并以图形方式显示结果。路径的彩色带很好。
请帮我在 Mathematica 中编写这样的功能。非常感谢!

这是一种可能性。
pos = {{1, 1}, {1, 2}, {2, 2}, {3, 3},
{3, 4}, {3, 5}, {4, 5}, {5, 5}};
mat = HankelMatrix[8];
display = Map[Pane[#,{16,20},Alignment->Center]&, mat, {2}];
display = MapAt[Style[#, Background -> Yellow]&, display, pos];
Grid[display, Spacings->{0,0}]
如您所述,用管子勾画条目更难。但是,如果我们愿意降级为图形基元,那么可以这样做。
mat = IdentityMatrix[8];
pos = {{1, 1}, {1, 2}, {2, 2}, {3, 3},
{3, 4}, {3, 5}, {4, 5}, {5, 5}};
pos = Map[{#[[1]], -#[[2]]} &, pos];
outline = {CapForm["Round"], JoinForm["Round"],
{AbsoluteThickness[30], Line[pos]},
{AbsoluteThickness[28], White, Line[pos]}};
disks = Table[{Darker[Yellow, 0.07], Disk[p, 0.25]},
{p, pos}];
numbers = MapIndexed[Style[Text[#, {#2[[1]], -#2[[2]]},
{-0.2, 0.2}], FontSize -> 12] &, mat, {2}];
Graphics[{outline, disks, numbers}, ImageSize -> 300]

另一种可能性,使用ItemStyle
:
m = RandomInteger[10, {10, 10}];
c = {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {5, 5}, {5, 6}, {5, 7}, {4, 8}};
Grid[m, ItemStyle -> {Automatic, Automatic, Table[i -> {16, Red}, {i, c}]}]
最终看起来像这样:

我可能误解了这个问题,但这是我认为你要求的:
coords = Join @@ Array[List, {3, 4}]
{{1, 1}, {1, 2}, {1, 3}, {1, 4}, {2, 1}, {2, 2}, {2, 3}, {2, 4}, {3,
1}, {3, 2}, {3, 3}, {3, 4}}
path = RandomSample[coords, Length[coords]]
{{1, 2}, {3, 3}, {2, 2}, {2, 4}, {3, 1}, {1, 4}, {1, 3}, {2, 1}, {3,
4}, {3, 2}, {2, 3}, {1, 1}}
labels = Text[StyleForm[#], #] & /@ coords;
Graphics[Line[path], Epilog -> labels]
