ALGLIB+

This is a extension of ALGLIB 3.12.0. ALGLIB+ will provide static liberary and some new functions which look like MATLAB function, such as interp1d, interp2d, etc.

Background

When I use deal.ii to develop a hydrothermal system simulator, the interpolation functions must be used to calculate fluid thermal properties at each pressure and temperture point. While the original ALGLIB does not provide a static or dynamic library to invoke and the arguments of interpolation function is a string type(you can see the examples), rather than a general C++ array. But I want a much easier way to invoke the interpolation function, to this end, I must to add some new functions, which simlar with MATLAB's function, to implement to my codes.

Therefore, ALGLIB+ is developed.

Compilation

ALGLIB just use the standard C++ library (that's very nice), so that makes compilation very easy. I have create a Makefile to do that. My system is MAC OS. Just change dir to ALGLIB+ dir, then use the following command: make to compile it. I think for the other UNIX/Linux system is similar.

How to use

Just include the src dir and add link of alglib.a.

Simple example

The source code of the example is in the example dir. The makefile as following.

CC = g++

INC_DIR = ../../src
LIB_DIR = ../../lib
interp1d: $(INC_DIR)/*.h obj
	$(CC) -o interp1d  splin_interp_1d.o $(LIB_DIR)/alglib.a 

obj: *.cpp 
	$(CC) -c  splin_interp_1d.cpp -I$(INC_DIR)

clean:
	rm *.o

With Deal.ii

Because the simple to use Deal.ii on Mac OS is as the example, do a little changes in the CMakeLists.txt to generate Makefile. You just use these two variables: INCLUDE_DIRECTORIES and link_libraries, to add include files and library. The cmake file just as following.

##
#  CMake script for the step-1 tutorial program:
##

# Set the name of the project and target:
SET(TARGET "dofs_play")
INCLUDE_DIRECTORIES("/Users/kakushi/Study/Programing/ALGlib/src")
link_libraries("/Users/kakushi/Study/Programing/ALGlib/lib/alglib.a")
# Declare all source files the target consists of. Here, this is only
# the one step-X.cc file, but as you expand your project you may wish
# to add other source files as well. If your project becomes much larger,
# you may want to either replace the following statement by something like
FILE(GLOB_RECURSE TARGET_SRC  "*.cc")

SET(TARGET_SRC
  ${TARGET_SRC}
  )

# Usually, you will not need to modify anything beyond this point...

CMAKE_MINIMUM_REQUIRED(VERSION 2.8.8)

FIND_PACKAGE(deal.II 8.5.0 QUIET
  HINTS ${deal.II_DIR} ${DEAL_II_DIR} ../ ../../ $ENV{DEAL_II_DIR}
  )
IF(NOT ${deal.II_FOUND})
  MESSAGE(FATAL_ERROR "\n"
    "*** Could not locate a (sufficiently recent) version of deal.II. ***\n\n"
    "You may want to either pass a flag -DDEAL_II_DIR=/path/to/deal.II to cmake\n"
    "or set an environment variable \"DEAL_II_DIR\" that contains this path."
    )
ENDIF()

DEAL_II_INITIALIZE_CACHED_VARIABLES()
PROJECT(${TARGET})
DEAL_II_INVOKE_AUTOPILOT()

Then use command of cmake . and make run to run the program of deal.ii example.
