宁以pass-by-reference-to-const 替换 pass-by-value (前者通常更高效、避免切割问题(slicing problem),但不适用于内置类型、STL迭代器、函数对象) 必须返回对象时,别妄想返回其 reference(绝不返回 pointer 或 reference 指向一个 local stack 对象,或返回 reference 指向一个 heap-allocated 对象,或返回 pointer ...

断言,是宏,而非函数。assert 宏的原型定义在<assert.h>(C)、<cassert>(C++)中,其作用是如果它的条件返回错误,则终止程序执行。可以通过定义NDEBUG来关闭 assert,但是需要在源代码的开头,include <assert.h>之前。 使用 代码语言:javascript 代码运行次数:0 ...

GENA_USE_SAMPLE– pass/return by value GENA_USE_ENTITY– pass/return by reference It is also a good practice to place library header inclusion and vector types instantiation in a separate header. Modular approach The main disadvantage about static approach is that vector type and it's correspond...
If your C functions accept only scalar and/or vector inputs, the Default function array layout setting has no effect. Call C Caller Block and Specify Ports You can start your custom C code integration into Simulink by typing C Caller in the Simulink canvas. Alternatively, drag a C Caller ...
