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?

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
% Remove the node 1
G = rmnode(G,1);
% Plot the graph
figure
plot(G)
