External Code Integration

Call external code from MATLAB^®code

When you have external code, custom code, or legacy code developed in C/C++, you can integrate it directly into your MATLAB code. To call C/C++ functions, use thecoder.cevalfunction. To pass data types to or from the external code that are not definable in MATLAB code, such as pointer types,FILEtypes for external file I/O, or other types, usecoder.opaque. Configure your build to include and link to external source files, header files, object files, and libraries by usingcoder.updateBuildInfo. To provide an object-oriented interface to an external C library, package your function calls into a class derived fromcoder.ExternalDependency.

Classes

`coder.ExternalDependency`	Interface to external code
`coder.BuildConfig`	Build context during code generation

Functions

`coder.ceval`	Call external C/C++ function
`coder.ref`	Indicate data to pass by reference
`coder.rref`	Indicate read-only data to pass by reference
`coder.wref`	Indicate write-only data to pass by reference
`coder.cinclude`	Include header file in generated code
`coder.opaque`	Declare variable in generated code
`coder.reservedName`	Generate code that does not use specified identifier names
`coder.updateBuildInfo`	Update build information object`RTW.BuildInfo`
