# AllIsomorphicQ¶

GraphISO.AllIsomorphicQ(folder, graphRange=None, info=True, checkSelf=False)

Calculates whether each pair of graphs (in a specified set of graphs) are isomorphic, returning an array $$R$$ with $$R_{ij} = 1$$ if graphs $$i$$ and $$j$$ are isomorphic, and $$R_{ij} = 0$$ otherwise.

Parameters: folder (str) – path to a folder containing a collection of adjacency matrices in dense text file format. graphRange (array) – an array containing graph numbers to test. By default, all graphs in a folder are tested. info (bool) – if True, information on each $$R_{ij}$$ comparison is printed to the console. checkSelf (bool) – if True, each graph is also tested against itself. array of ints

Note

The text files must have filenames of the form *X.txt where X represents a number (of any number of digits). These are used to order the graphs.
