Hi, Dr. Liu,
I like your refactorization software sxamg. I am trying to plugin it to solve a 3D Maxwell equation (complex in frequency domain which has been converted into a rea-valued linear system Ax=bl). Unfortunately, the code runs into AMG setup stage without exist for hours.
I do not know why, because I was able to run your examples of 3D Poisson equation successfully. Can you give me some help?

I think you have made a lot of optimization for sxamg in grid coarsening. But I was unable to figure out what has been implemented exactly. Typically, op-coarsen.c is the one I am looking at. Can you provide a reference or paper which you were following?

Any help would be highly appreciated!

Best regards,
Pengliang

Hi,
I want to learn and use the sxamg you developed, but after I type make install, there are some errors：

make[1]: Entering directory '/home/txt/Downloads/sxamg-master/src'
make[1]: Nothing to be done for 'default'.
make[1]: Leaving directory '/home/txt/Downloads/sxamg-master/src'
cp: cannot stat 'lib/libsxamg.a': No such file or directory
Makefile:28: recipe for target 'install' failed
make: *** [install] Error 1

Whether I use ./configure, make, sudo make install or ./configure --prefix/xx/xx, make, make install will have this problem, the installation directory has only one empty folder lib

Hi,
When I was reading your code, I saw a variable verb. I'm sorry I didn't understand the function of the variable. Could you please tell me the details of the variable?
For example, in example/amg.c
pars.verb = 3;

Thanks!
