remove nodes without changing the numbering of nodes

I have a graph from which I want to remove nodes but want to keep the labels or the numbering of the nodes as the same before removing nodes. Is that possible with some option?

[MUHAMMAD USMAN]

When we have 100 of nodes, how can we assigned a label by writting the following command.

G = graph(s,t,[],{'1','2','3','4', ..., '100'});

There is some other way to assign a label to large-size network?

How about setting a nodelabel for each node?

The following is an example:

s = [1 1 1 2 2 3];
t = [2 3 4 3 4 4];

% Create a graph G with nodelabel '1',...,'4'
G = graph(s,t,[],{'1','2','3','4'});

% Remove the node 1
G = rmnode(G,1);

% Plot the graph
figure
plot(G)

If you have too many nodes to manually create the cell array of node names, use a string array.

s = [1 1 1 2 2 3];
t = [2 3 4 3 4 4];

names = string(1:4);
% Create a graph G with nodelabel '1',...,'4'
G = graph(s,t,[], names);
G.Nodes

ans = 4×1 table
    Name 
    _____

    {'1'}
    {'2'}
    {'3'}
    {'4'}

% Remove the node 1
G = rmnode(G,1);

% Plot the graph
figure
plot(G)
