number of spatial nodes in matlab

To calculate the number of spatial nodes in MATLAB, you can use the numnodes function from the MATLAB built-in graph object.

Here is an example of how you can use it:

main.m
% Create a sample 2D graph with 5 nodes
G = graph([1 2 3 4 5], [2 3 4 5 1]);

% Calculate the number of spatial nodes
numSpatialNodes = numnodes(G);

% Display the result
disp(numSpatialNodes);

In this example, we create a graph G with 5 nodes and then use the numnodes function to calculate the number of spatial nodes. The result is then displayed using the disp function.

The output will be the number of nodes in the graph, which in this case is 5.
