=== Explanation of what I want to do with each file === | |||
Each FORTRAN file that need to be linked to an Oct file needs work done on it. I plan to take the following steps with each FORTRAN program: | |||
# Change the FORTRAN program into a subroutine. The arguments of this subroutine will be the parameters that this program would have normally read from the user during execution. | |||
# Move input parsing and validation from the FORTRAN files to the .cc file which will link the respective fortran file to it. This will make the fortran subroutines 'dumb' and unable to distinguish between good and bad data. | |||
# Eliminate all file inputs and outputs. The fortran programs write and read data to/from files. This is unnecessary in Octave, as data can be supplied and retrieved to/from these subroutines directly via oct files. | |||
# Test the oct file against the original library to ensure I didn't make mistakes. | |||
I plan to do similar steps for the c files. I believe this stage will be easier as the c code is much better organized and eliminating input validation & parsing, file inputs and outputs should be a much easier task. | |||
