Your next steps may require little more than multiplying the result array by the column vector of numbers and allowing the calculation to broadcast the vector over the array. Similarly multiplication by a factor of 1000 would be applied to every element of the array. T...

lambda表达式存在的意义:使语法更加简洁,逻辑更加清晰,如果传入的是指针函数,那么编译器通常不会将其内联展开,但是如果是lambda表达式,编译器可能会将其内联展开,减少函数调用的开销。每当你定义一个lambda表达式后,编译器会自动生成一个匿名类(这个类当然重载了()运算符),我们称为闭包类型lambda表达式有俩种捕获值得...
