We simply move the new values for the parameters on top of the old ones and do a jump to the point in the function right after local variables are saved on the stack.

OK, so last time we saw how to use Lagrange multipliers to find the minimum or maximum of a function of several variables when the variables are not independent.
上次我们看了，怎样利用拉格朗日算子，去求解一个受约束的，多变量函数的最大最小值。
If you have a function of 30 variables, things work the same way, just longer, and you are going to run out of letters in the alphabet before the end.

The optimal value of the relaxed objective function (the one that didn't consider the decision variables as integers) is also printed here.
放松限制的目标函数(不将决策变量当作整数考虑)的优化值同时也给出来了。
The function begins with the declaration of a variety of needed variables and structures.
函数开始是声明所需变量和结构。
So, we said when we have a function of two variables, we have the gradient vector.
我们说，当一个二元函数存在时，就有梯度向量。
Variables to be imported from the outside environment are specified in the use clause of the closure function definition.
从外部环境中导入的变量是在闭包函数定义的use子句中指定的。
The tcp_close function updates three variables of the routing metrics structure, and then releases the resources held by the socket.
tcp_close函数更新路由度量结构的三个变量，然后释放套接字持有的资源。
Let's first consider how to return the output of the XMLQuery function to variables declared in a stored procedure.
我们首先考虑如何将XMLQuery函数的输出返回给存储过程中声明的变量。
Most of the variables used in RunSearch are defined at the beginning of the function.
runsearch函数开头处定义了它所用到的绝大多数变量。
The line xdebug.show_local_vars = 1 prints all local variables in the outermost scope of each function call, including variables not yet initialized.
代码行 xdebug.show_local_vars =1将打印每个函数调用的最外围中的所有局部变量，包括尚未初始化的变量。
A number of variables have special meanings that are a function of the rule they're being used in. The most commonly used are
很多变量都有一些特殊的意义，这是正在使用它们的规则的一种功能。
In Python, you obtain the value of these variables with a single call to the os.environ.get function as follows.
在Python中，通过对os . environ . get函数的一个调用来获取这些变量的值，具体如下。
Another limitation of SOP is that it USES the toString function to serialize the variables and therefore cannot be used for complex variables by default.
SOP的另一限制是使用toString函数将变量序列化，因此缺省情况下它不能用于复合变量。
Typically, the setup function contains the size function (to define the bounds of the window) as well as initialization of variables that are used during operation.
通常，setup函数包含size函数(用于定义窗口的边界)以及在操作期间要使用的变量的初始化。
Calling a generator function a second (or NTH) time jumps into the middle of the function, with all local variables intact from the last invocation.
对生成器函数的第二次(或第n次)调用跳转至该函数中间，而上次调用的所有局部变量都保持不变。
That is, a closure is an anonymous function that, when created, attaches to itself the value of variables from the scope of the code that created the function.
就是说，closure是个匿名函数，在其创建时，将来自创建该函数的代码范围内得变量值附加到它本身。
Variables that are a part of a % FUNCTION block, and they can only to be referenced within that block.
