Introducing the Target Language Compiler (Target Language Compiler)

Target Language Compiler

Search Algorithm for Locating Target Files

The Target Language Compiler has the following search path for block target files:

The current directory
The directory where the S-function executable (MEX or .m) file is located
S-function directory's subdirectory ./tlc_c (for C language targets)

The first target file encountered with the required name that implements the proper language will be used in processing the S-function's model.rtw file entry.

Availability for Inlining and Noninlining

S-functions can be written in M, Fortran, and C. TLC inlining of S-functions is available as indicated in this table.
