Suppose f of x, y, z equals k1, that is my equation, s1 and it gives me a solution s1.
假设我的方程是这样,然后给出了一个解。
The power of linearity is F=k1+k2 if I come across f of x, y, z equals k1 plus k2, if it is a linear equation, I don't have to go and solve it all over again.
线性的威力是,一个方程,如果它是个线性方程,那么我就不用再去解他了。
That statement says, get the value of x, which is this link, and give z a pointer to the same place.
这个声明的意思是,取得x的值,也就是连接指向的值,然后给z赋予一个指向同样位置的指针。
