This is the code used in the paper Deterministic Column Sampling for Low-Rank Matrix Approximation: Nyström vs. Incomplete Cholesky Decomposition, R. Patel, T. Goldstein, E.L. Dyer, et al., SIAM Data Mining Conference, 2016.
Specifically, this code implements: oASIS in MATLAB, oASIS in MATLAB with mex, and oASIS-P in C++.
We also include a MATLAB function to generate BORG datasets.
