InterfaceTest_simple.cpp File Reference

This c++ driver illustrates the c++ interface to ButterflyPACK's Fortran subroutines for compression a kernel ridge regression (KRR) matrix, with the entry-evaluation-based APIs. This file works on the double data type. This file is a simplified version of InterfaceTest.cpp which provides more examples. More...
