Zemax软件中，merit function（ merit 函数）计算失败的问题常常困扰用户。要正确解决这一问题，用户首先需要明确的是，在软件中选择正确的行至关重要。只有选择了正确的行，才能在随后的界面上看到目标（target）和权重（weight）的设置。如果选择的行不正确，这些关键设置将不会显示，从而导致merit funct
光线在半路被损失掉了，因此你设置的成像面没有探测到你指定的光线，所以会出现这个问题。比如说0.8像场的光线已经在前面的原件中损失掉了，而你的优化函数中还有0.8像场的优化目标，所以会报错。如何避免，1 光路更加合理，2 可以将像场降低一些，慢慢往上加。3 设定每一个面上的光线的高度，并且...
Any definite numerical quantity or other mathematical object, determined by being measured, computed, or otherwise defined. The exact value of pi cannot be represented in decimal notation. Merit Reward deserved; any mark or token of excellence or approbation; as, his teacher gave him ten merits....
Thus, when the CNR is computed, both numerator and denominator are null, thus producing a NaN output. When considering the results obtained for the realistic system, it is possible to notice a different trend in the C function. In particular, while a delta-Dirac response produces C functions...
5The formulation of the cost function in equation (1) can in any case be interpreted in terms of devoted worker in a more traditional way. In fact dij can be interpreted as a lower cost that derives from the devoted characteristic of the staff. In this model we assume that d is ...
