Question

我在MATLAB中创建了以下class Timesheet(models.Model): owner = models.ForeignKey(User, on_delete = models.CASCADE) title = models.CharField(max_length = 64, verbose_name = _("Title")) start = models.DateTimeField(verbose_name = _("Start time")) end = models.DateTimeField(verbose_name = _("End time")) allDay = models.BooleanField(blank = True, default = False, verbose_name = _("All day"), help_text = _("If it's a full day work, just click 'Now' for start/end")) week = models.IntegerField(verbose_name = "working week") def __str__(self): return "{}".format(self.title) def save(self, *args, **kwargs): if not self.pk: self.week = datetime.datetime.now().isocalendar()[1] if self.allDay: self.start = datetime.datetime(year = datetime.datetime.today().year, month = datetime.datetime.today().month, day = datetime.datetime.today().day, hour=8, minute=00) self.end = datetime.datetime(year = datetime.datetime.today().year, month = datetime.datetime.today().month, day = datetime.datetime.today().day, hour=17, minute=30) super(Timesheet, self).save(*args, **kwargs)

Graph

我想在两个连续的节点之间添加节点。

我正在尝试以下方法

1。获取function dummyGraph() tail = [1 2 3 4 5 6 6 7 8 9 10 10 12 13 14 15]; head = [2 3 4 5 6 7 12 8 9 10 15 11 13 14 15 16]; Graph = graph(tail,head) plot(Graph) NodeNumber = 1:16 Neighbor={}; for NodeIdx =NodeNumber Neighbor{NodeIdx} = neighbors(Graph,NodeIdx); end end中存在的所有节点的邻居节点。 2.在两个连续的邻居之间添加四个新节点。

我可以在代码中实现第一步。我找不到用于在现有节点之间添加节点的MATLAB命令。 MATLAB文档中提供了命令Graph。但是，我不确定如何使用此命令来实现我的情况。

我想征求有关如何进行的建议

Answer 1

这是解决方案，

function AddNodes()
tail = [1 2];
head = [2 3];
Graph = graph(tail,head)
NVertex = size(Graph.Nodes);
NVertex = NVertex(1);

%% Name Nodes

NNode = string(1:NVertex)';
Graph.Nodes.Name = cellstr(NNode);


%% Adding nodes
GraphEdges = table2cell(Graph.Edges(:,1));
NEdges = size(GraphEdges);
NEdges = NEdges(1);
Source=[];
Sink =[];
for edge = 1:NEdges
    Graph  = addnode(Graph,4);
    source = GraphEdges{edge}(1);
    sink = GraphEdges{edge}(2);
    Graph  = rmedge(Graph,source,sink); 
    Add4Musk = Graph.Nodes.Name(end-3:end);
    TobeAdded  = vertcat(source,Add4Musk,sink);
    for node = 1:length(TobeAdded)-1
        source = TobeAdded(node);
        sink = TobeAdded(node+1);
        Graph = addedge(Graph,source,sink);
    end 
end

%% Plot graph
plot(Graph,'Layout','subspace3')

很高兴知道是否还有其他方法可以完成此任务。
