nufft_comparison Comparing the speeds between various nufft implementations Compilation is not quite straightforward at this point, but here's what you can try: Create the mex for the fortran version > cd nufft-1.33-mcwrap > compile_mex_nufft > cd .. If you want to access the fortran versions directly use > addpath nufft-1.33-mcwrap Create the mex for the C++ version - a bit more complicated Not having an easy time using openmp in mex... so you must first creat a .o file: > cd blocknufft > g++ -fopenmp -c blocknufft3d.cpp block3dspreader.cpp -fPIC -O3 That's for Linux... need to do equivalent for other OS Then in MATLAB > cd blocknufft > compile_mex_blocknufft3d Now take a look at do_compare_01.m There are various options to do various things. Sorry, no more details at this point. Run FESSLER at your own risk -- uses up a lot of RAM, depending on size of data.
