Pride-pppar source code analysis

1、 install PRIDE—PPPAR
Know this software is brush know （ID： Lost little bookboy ）, The software is introduced in the article written by the geodetic doctor of Wuhan University , I read his article on the basis of , It comes from practice .
Wuhan University PRIDE The research group is open source PPPAR, It can be found on its official website or GitHub Find the download link on . The manual details the installation steps of the software 、 The code framework 、 Each step produces the definition of the document , After reading the manual , Think I can , I can start .
（1） stay Windows Lower installation vm virtual machine , Install... On the virtual machine Ubuntu System , Check whether the compiler is installed .
（2） Open... Under the corresponding path in the terminal according to the manual *.sh File can . Just perform two steps *.sh File can generate the result process file .
Super convenience ~ Better than before GAMIT Much simpler
2、PRIDE-PPPAR Source code usage
As an algorithm worker , What I care about most is src Everything in the folder . Each folder corresponds to a program,n individual subprogram.
Share my experience of looking at the source code .
（1） Be sure to look at the source code framework first , Combined with chapter 4 Part of the frame diagram and src Folder , You know that the bold function name of the frame diagram is the main program program, Find the corresponding folder and file , such as Tedit, Went to src Medium Tedit Folder , stay Tedit Look in the folder tedit.f90 File can ;
（2） You need to master the basic Fortran grammar , Grammar doesn't necessarily need to be proficient , But you need to be familiar with its usage , I simply read a file , I don't know %、:: Etc , I went to Fortran Information , In fact, on the basis of mastering other languages , It's fast to learn other languages . I checked the data and found , From China University of science and technology Fortran The courseware is very good （http://micro.ustc.edu.cn/Fortran/ZJDing/）, Go directly to the data structure , Find out what you need , have a definite object in view , Don't waste time .
（3） According to the manual recommendations , Installed codeblocks（ Set the editor eye protection , Font size ）, Open the source code directly .cbp file ; If you sometimes look at the source code and find that the function is not specifically implemented （ The function interface ）, That is because it is encapsulated in the dynamic link library so It's in the library , have access to readelf -a so File path You can go to Windows Check the function interface .
（4） most important of all , Want to have PPP Basic theoretical basis ！
