Webb7 sep. 2024 · If the code is provided as a homework laboratory exercise, be certain you have downloaded all the functions relevant to it, and copied them to an appropriate directory on your MATLAB search path. The ‘plotspec’ function is likely one of them, and I assume that ‘shortSinus’ is also one of them. WebbTypeScript 中有的函数重载并不是定义几个同名实体函数,然后根据不同的参数个数或类型来自动调用相应的函数。而是在类型系统层面的,是为了更好地进行类型推断。TypeScript的函数重载通过为一个函数指定多个函数类型定义,从而对函数调用的返回值进 …
