# Bottleneck_distance #

## `bottleneck_read_file_example` ##
This program computes the Bottleneck distance between two persistence diagram files.

Usage:
`bottleneck_read_file_example <file_1.pers> <file_2.pers> [<tolerance>]`
where
`<file_1.pers>` and `<file_2.pers>` must be in the format described [here](http://gudhi.gforge.inria.fr/doc/latest/fileformats.html#FileFormatsPers).
`<tolerance>` is an error bound on the bottleneck distance (set by default to the smallest positive double value).
