invertible matrix


I am building a markov chain model from different transition matrices; some
of my matrices are singular and its inverse cannot be retrieved. I am
wondering if there is any igraph method to import my transition matrix and
to transform it into a subgraph that is invertible.

Many thanks,


It’s not clear to me what you mean by “transform it into a subgraph that is invertible”. Can you clarify, preferably through a small example?
