配置编译设置

指定编译类型

编译类型

MATLAB® Coder™ 可以生成以下输出类型的代码:

  • MEX 函数

  • 独立 C/C++ 代码

  • 独立 C/C++ 代码并将其编译为静态库

  • 独立 C/C++ 代码并将其编译为动态链接库

  • 独立 C/C++ 代码并将其编译为可执行文件

使用 MATLAB Coder App 生成 C 可执行文件

此示例说明如何使用 MATLAB® Coder™ App 从 MATLAB 代码生成 C 可执行文件。在此示例中,您为 MATLAB 函数生成一个可执行文件,该函数用于生成随机标量值。使用该 App 可以执行以下操作:

  1. 生成示例 C main 函数,该函数调用生成的库函数。

  2. 复制并修改生成的 main.c 和 main.h

  3. 修改工程设置,以便 App 可以找到修改后的 main.c 和 main.h

  4. 生成可执行文件。

When generating C/C++ code from MATLAB® code, the code generator automatically produces two housekeeping functions, initialize and terminate. The initialize function initializes the state on which the generated C/C++ entry-point functions operate. It must be called before you call the entry-point functions for the first time. The terminate function frees allocated memory and performs other cleanup operations. It must be called after you call the entry-point functions for the last time.

当您编译使用生成的 C/C++ 代码的应用程序时,必须提供调用生成的代码的 C/C++ 主函数。

默认情况下,对于 C/C++ 源代码、静态库、动态库和可执行文件的代码生成,MATLAB® Coder™ 会生成示例 C/C++ 主函数。此函数是可以帮助您将生成的 C/C++ 代码合并到应用程序中的模板。示例主函数声明和初始化数据,包括动态分配的数据。它会调用入口函数,但不使用入口函数返回的值。

MATLAB Coder 在编译文件夹的 examples 子文件夹中生成示例主函数的源文件和头文件。对于 C 代码生成,它会生成 main.c 和 main.h 文件。对于 C++ 代码生成,它会生成 main.cpp 和 main.h 文件。

不要修改 examples 子文件夹中的 main.c 和 main.h 文件。如果修改这些文件,则当您重新生成代码时,MATLAB Coder 不会重新生成示例主文件。它会发出警告,提示检测到生成文件发生了更改。在使用示例主函数之前,将示例主函数源文件和头文件复制到编译文件夹以外的某个位置。修改新位置的文件以满足您的应用程序的要求。

当您使用默认配置设置生成文件时,MATLAB Coder App 的 packNGo 函数和 Package 选项不会打包示例主函数源文件和头文件。要打包示例主文件,请配置代码生成以生成和编译示例主函数,生成代码,然后打包编译文件。

Bluetooth LE Node Statistics

The Bluetooth low energy (LE) network simulation captures these statistics as a structure. This structure is returned as an output by the statistics object function of the bluetoothLENode object. The fields of this structure depend on the value of the Role property of the bluetoothLENode object.
