所谓的子串(token)就是指编译器能够识别的最小语法单元。具体的定义在编译原理里有详尽的解释，但不知道也无所谓。同时值得注意的是#符是把传递过来的参数当成字符串进行替代。例如 define A(x) t_##x A(i)实际定义就是 t_i;define _VECTOR(N) __vector_ ## N 也是一样 _VECTOR(io)实际定...
A vector is defined as an object, in mathematics, that has both magnitude and direction. The magnitude of the vector represents the size.Two vectors are said to be equal if their magnitude and direction are the same. Components of the vector : The length of the segment of the directed lin...

1. Define an integer vector and get several input from keyboard, then display the numbers in the vector. The for loop is required to write the display loop. 2. Declare a vector container. Using keyboard to input several integer numbers, say at ...
I would like to define a symbolic vector like y = [0 1]*x where x is [x1 ; x2]. So basically y actually equals to x2. Is it possible?댓글 수: 0 댓글을 달려면 로그인하십시오.이 질문에 답변하려면 로그인하십시오.채...

The situation is, input A as a m*1 vector, like [1,2,3]; after calculation in a equation we get output B (result is a m*1 vector); then another vector input C, n*1, is involved; after input in another equation (contain both B and C) for calculation, we get result D, which...
