简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 c$f|a$$b UQ|zSalv, 配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： ^H+j;K{5, enableservice('AutomationServer', true) c ;3bX6RD* enableservice('AutomationServer') p71% -nV  nf< <]iHf 结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 (PYUfiOf S(A0), 在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： zIbl[ [M& 1. 在FRED脚本编辑界面找到参考. ;{|a~e?Y 2. 找到Matlab Automation Server Type Library Q6S[sTKR 3. 将名字改为MLAPP X7kJWX IidZ -Il $8&HpX#h$ 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 )!dELS \ix 8Gb=aF1 图 编辑/参考 /x_C -<# n7b 现在将脚本代码公布如下，此脚本执行如下几个步骤： ?xf59mY7 1. 创建Matlab服务器。 | -Di/. 2. 移动探测面对于前一聚焦面的位置。 '4sT+q 3. 在探测面追迹光线 F *;
