Webf2c / f77 background. f2c is a fortran77-to-c source code translator. Because f2c is written in c and its ouput is c, both of which can be compiled natively on unix operating systems, f2c offers a very transportable compiler solution for compiling fortran programs. f2c also offers a means of converting large fortran libraries, such as LAPACK ... f2c is a program to convert Fortran 77 to C code, developed at Bell Laboratories. The standalone f2c program was based on the core of the first complete Fortran 77 compiler to be implemented, the "f77" program by Feldman and Weinberger. Because the f77 compiler was itself written in C and relied on a C compiler back end to complete its final compilation step, it and its derivatives like f2c were much more portable than compilers generating machine code directly.

WebThe specification of the automatic Fortran-to-C translation program f2c can be summarized thusly: f2c attempts to create C code whose functionality is identical to that of the source Fortran code. Due to limitations of C and the system-dependent behavior of Fortran I/O, f2c cannot always completely succeed in fulfilling its nominal specification. WebMar 16, 2024 · Then all you have to do is to convert the Matlab variables to the equivalent representation of FORTRAN variables. I've used f2c successfully to do this with an integrator. The original code has over 100'000 lines of code. Calling C from Matlab is easy also. Rather than trying to convert each line of Fortran code into MATLAB, if you do …
