The embedded function "allSimplePaths" in the allpaths.m

I am working on revising the source code in the script("allpaths.m"). My matlab version is R2022b. I understand that in the script there is another function called allSimplePaths which computes all simple paths from a node to another for a graph. However, I can not locate this function in the MATLAB documents. I tried to use F4 to locate but the editor gave me a error "the fie does not exist, do you want to create one?"

Does anyone have the question like this? Thanks in advance.

I strongly recommend that you not modify functions included in MATLAB or other MathWorks products.

Ok, thanks.

What modifications were you hoping or planning to make to allpaths?

Answer 1

[Walter Roberson]

allSimplePaths is a built-in method % matlab.internal.graph.MLDigraph method

It is an undocumented internal function.

Thank you for the explanation.
