!> @brief High-order compact finite difference scheme (generalized Padé scheme) solver with specific order of accuracy.
!!
!! 이 모듈은 high-order compact 차분 스킴을 정의하고 수치 미분을 수행합니다.
!! Compact 차분 스킴은 implicit 스킴이므로, 모듈 내부에서 implicit 연산을 빠르게 해결하기 위해
!! tridiagonal matrix solver(stdlu, ptdlu 등)가 함께 구현되어 동작합니다.
!! This module handles the generation of tridiagonal/pentadiagonal matrices,
!! LU decomposition calculations, and tridiagonal solver operations (such as stdlu, ptdlu, etc.)
!! for periodic and non-periodic boundary conditions. Since compact finite difference schemes
!! are implicit, these solvers are implemented internally to perform numerical differentiation
!! by solving the implicit relations efficiently.

!> @brief 유동 도메인(Flow domain)이 정의되었을 때 x, y, z 방향에 적절한 compact 차분 스킴을 매칭하고 캐시(Cache) 관점의 계산 최적화를 수행하는 모듈입니다.
!> @brief DNS post-processing mathematical operations and derivatives, matching appropriate compact schemes in X, Y, Z directions for a defined flow domain and optimizing calculations from a cache perspective.
!!
!! 이 모듈은 3차원 유동 도메인 필드 데이터를 입력받아 각 차원 방향으로 수치 미분을 행합니다.
!! 특히 1차 및 2차 공간 미분(ddx, ddy, ddz 등)을 고차 컴팩트 스킴으로 해결하며,
!! 메모리 캐시 효율성(Cache blocking) 및 전치(Transpose) 최적화 연산(`tp2`)을 포함하고 있습니다.
!! This module calculates spatial derivatives (first and second spatial derivatives in X, Y, Z directions like ddx, ddy, ddz, etc.)
!! using high-order compact finite difference schemes. It also calculates chemical reaction rates,
!! positive/negative component extraction, and threshold operations, incorporating memory cache
!! efficiency (cache blocking) and transpose optimization operations (`tp2`).
