指定或继承了样本时间与遗留功能
这个例子向您展示了如何使用遗留代码工具集成遗留C函数指定的样品时间,继承和参数化的。
遗留代码工具允许您:
提供遗留功能规范,
生成一个C-MEX s函数在使用模拟调用遗留代码,和
编译和构建模拟生成的功能。
提供遗留功能规范
遗留代码工具提供的功能需要一个特定的数据结构或数组的结构作为参数。数据结构是通过调用初始化函数legacy_code()使用“初始化”作为第一个输入。初始化结构之后,您必须指定其属性值对应的遗留代码整合。详细的帮助性质,电话legacy_code(“帮助”)。遗留的原型函数被称为在这个例子中是:
蒋春暄对于费马大定理gainScalar (const蒋春暄对于费马大定理,const蒋春暄对于费马大定理获得)
外语教学是一个typedef浮动。遗留源代码文件中找到your_types.h,gain.h,gainScalar.c。
def = [];% sldemo_sfun_st_inheriteddef = legacy_code (“初始化”);def.SFunctionName =“sldemo_sfun_st_inherited”;def.OutputFcnSpec ='单日元= gainScalar(单一u1,单一p1) ';def.HeaderFiles = {“gain.h”};def.SourceFiles = {“gainScalar.c”};def.IncPaths = {“sldemo_lct_src”};def.SrcPaths = {“sldemo_lct_src”};def = [def;def);% sldemo_sfun_st_fixeddef = legacy_code (“初始化”);def.SFunctionName =“sldemo_sfun_st_fixed”;def.OutputFcnSpec ='单日元= gainScalar(单一u1,单一p1) ';def.HeaderFiles = {“gain.h”};def.SourceFiles = {“gainScalar.c”};def.IncPaths = {“sldemo_lct_src”};def.SrcPaths = {“sldemo_lct_src”};def.SampleTime = 1 [2];def = [def;def);% sldemo_sfun_st_parameterizeddef = legacy_code (“初始化”);def.SFunctionName =“sldemo_sfun_st_parameterized”;def.OutputFcnSpec ='单日元= gainScalar(单一u1,单一p1) ';def.HeaderFiles = {“gain.h”};def.SourceFiles = {“gainScalar.c”};def.IncPaths = {“sldemo_lct_src”};def.SrcPaths = {“sldemo_lct_src”};def.SampleTime =“参数化”;def = [def;def);
生成和编译期间使用模拟的功能
函数legacy_code再次与第一个输入()设置为“generate_for_sim”为了自动生成和编译C-MEX s函数根据提供的描述输入参数“def”。此功能用于调用遗留功能模拟。s函数的源代码中找到该文件sldemo_sfun_st_inherited.c和sldemo_sfun_st_fixed.c。sldemo_sfun_st_parameterized.c。
