使用预置的 MATLAB C++ 库接口

要调用 C++ 库中的函数，请使用 MATLAB^® clib 命名空间

如果您有已发布的对接 C++ 共享库的 MATLAB 接口，则可以直接在 MATLAB 中使用这些类和函数，从而在 MATLAB 和 C++ 之间来回传递数据。

函数

`clibArray`	为 C++ 库函数创建 MATLAB clib 数组
`clibConvertArray`	将 MATLAB 基本数组或结构体数组转换为 C++ 对象的 MATLAB 数组
`clibConfiguration`	Set run-time configuration parameters for C++ library interface (自 R2023a 起)
`CLibraryConfiguration`	C++ library interface environment information (自 R2023a 起)
`clibIsNull`	确定 C++ 对象是否为空
`clibIsReadOnly`	确定 C++ 对象是否为只读
`clibRelease`	从 MATLAB 中释放 C++ 对象
`underlyingValue`	在 MATLAB 中创建的 C++ 枚举对象的基础数值

配置 C++ 库接口

Set Run-Time Library Path for C++ Interface
If the C++ library has a compiled library file, then that file and its dependencies must be on your system path or run-time search path (rpath).
Load C++ Library In-Process or Out-of-Process
Execute C++ functions in processes that are the same as or separate from the MATLAB process.

在 MATLAB 中使用 C++ 库

Call Functions in C++ Compiled Library

To call a function in the library, use the MATLAB clib namespace.
- Pass struct Parameter
- Pass const and Non-const Parameters
- Pass C++ Language Opaque Objects
- Pass Functions as Arguments
- Use Function and Member Function Templates
- Pass std::vector Parameter
- Pass Fixed-Sized Array Parameter
- Pass Parameter by Reference
- Handle Updated Array Elements
Pass clib.array to C++ Functions
The term clib array is the MATLAB object representation of C++ native arrays and std::vector types.
Create MATLAB Array of C++ Objects
Call clibArray to create MATLAB clib array for C++ library functions.
MATLAB Type to C++ Type Mapping
When you pass MATLAB data as arguments to C++ methods or functions, MATLAB converts the data into types that best represent the data to the C++ language.
