bottleneck

C++ code for calculating bottleneck distance between two peristence diagrams with mex code for Matlab interop

Based on the Hopcroft-Karp algorithm

Compiling

Depends on g++ compiler

make

Building for Matlab

From the Matlab command line, run

cd <THIS_DIRECTORY>
mex bottleneck_distance.cpp

Then from your Matlab code you can call

bottleneck_distance(mat1, mat2)

where mat1 and mat2 are two Mx2 matrices representing persistence diagrams. The function outputs the distance between the two matrices.

Running on the command line

You can also run from the command line if you have saved the persistence diagrams to files

./bottleneck pers_dia1.txt pers_dia2.txt

Testing

run test_bottleneck.sh

./test_bottleneck.sh
