谁把光学传递函数详细阐述一下
The merit function is proportional to the square root of the weighted sum of the squares of the difference between the actual and target value of each operand in the list. The merit function is defined this way so a value of zero is ideal. The optimization algorithm will attempt to make the value of this function as small as possible,and so the merit function should be a representation of what you want the system to achieve. You do not have to use the default merit function, you may construct your own.
