Python中有一个有趣的语法,只要定义类型的时候,实现__call__函数,这个类型就成为可调用的。换句话说,我们可以把这个类的对象当作函数来使用,相当于重载了括号运算符。 class Student(object): def __init__(self, name): self.name = name def __call__(self): print('My name is %s.' % self.name...

build时就会报错了,更别提执行了 怎么做呢?需要把Kernel的函数封装到一个Handler里,然后把这个Handler注册到系统的System Call Group里。然后,RTP里通过操作系统提供的Trap来访问这个Handler。 第一步:在Kernel里创建struct数据类型,用来表示Kernel函数的入参
To call a MATLAB script or function, put it on your MATLAB path. For other options, seePut Function on Python Path. For this example, create a MATLAB script in a file namedtriarea.min your current folder. b = 5; h = 3; a = 0.5*(b.* h) ...
