interpolation with multi-dimensional grid data
Suppose we want to interpolate a multi-dimensional function
y = f(x1, x2, x3...)
and we have numerical table of values at grid points of each axis.
This interpolation can be done by using scipy.interpolate.interpn
However, the data have to be prepared in specific forms.
scipy.interpolate.interpn(points, values, xi, method='linear', bounds_error=True, fill_value=nan)
(1) "points" are tuple of grid points in each axis.
points = ( [array of possible grid points in 1st axis], [array of possible grid points in 2nd axis],...)
in other words, points=(x1,x2,...xn) such that xn[i] gives i-th grid value in n-th axis.
(2) "values" are n-dimensional array such that
value[ i1][i2][i3]...[in] = f( x1[i1], x2[i2],..., xn[in] )
(3) "xi" is a coordinate to sample the value

Let us list impact factors of related with my research. (may be not so recent.)
I am surprised that the rank of Physical Review C is not so high.

Creating personal library in Linux : 1. Fortran library to be used in Fortran (working)
The purpose of this post is to summarize the procedure to make personal library of routines so that re-use previous works.
(1) Fortran library to be used in Fortran
(2) C/C++ library to be used in C/C++
(3) Fortran library to be used in C/C++
(4) C/C++ library to be used in Fortran
(5) Fortran library to be used in Python
(6) C/C++ library to be used in Python
Let us start from the first/second case.
(1) to make a static library use "ar crvs"
ar rc liball.a dog.o cat.o bird.o #rc=replace/create
ranlib liball.a # make symbol indexing or use "s" for ar
to usegcc main.c -L -l<filename>
(2) to make dynamic/shared library use linker like "gcc" ,"gfortran"
gcc -g -fPIC -Wall -Werror -Wextra -pedantic *.c -shared -o liball.so
to use dynamic librarygcc -g -wall -o app app.c liball.so
* if source file *.f use .mod file, one have to keep them to make shared library.But once the shared library is created, .mod files are no more necessary.

tip: find "*.xxx" files recursively and remove them in linux
my solution: combine "find" and python
(1) find . -type f -name "*.xxx" > tt
(2) do following in python
import os
ff= open('tt','r');fnames=ff.readlines();ff.close()
for i in fnames:
os.remove(i[:-1]) # remove \n in the end
