MatrixExp_with_CMake

Using the provide code in src folder, modify the sample file

• CMakeLists.txt
• src/CMakeLists.txt

to be able to execute the complete workflow

• cmake .
• ccmake .
• make
• make test
• run

Note:

• The code is written in both c++ and fortran 90, so cmake should look know it

  • use enable_language (Fortran)

• It relies upon blas dgemm and lapack dsyev routine, so blas and lapack should be searched using the built-in modules

  • use

    • find_package (libname REQUIRED)
    • include_directories
    • target_link_libraries

• The code works with both c-style random number generators and c+11 new random generators.

  • try adding the following code to BUILD_DIR/CMakelists.txt

    option (USE_CXX11 "C++11 compatibiity, mostly for the random generator class" ON) if (USE_CXX11) set (CMAKE_CXX_FLAGS "-std=c++11") endif (USE_CXX11)

  This will add a switchable field, that can be modified using ccmake

• activate testing ( use "enable_testing()" )

• add a test

  :: add_test (MatrixExpId3 ${PROJECT_BINARY_DIR}/bin/MatrixExp 3 17 Id)

  set_tests_properties ( MatrixExpId3 PROPERTIES PASS_REGULAR_EXPRESSION "Difference between the two methods 0.00000000000000")

• have the executables built in the "bin" folder

  • use EXECUTABLE_OUTPUT_PATH
