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。 uH.1'bR?a 6eB2mcV 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: K'@lXA: enableservice('AutomationServer', true) Acl?w }Y enableservice('AutomationServer') ZR[6- .Xcf*$.;s 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。 7.W$6U5 Kt*kARN? 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: W|I<hY\X 1. 在FRED脚本编辑界面找到参考. *ujJpJZ2 2. 找到Matlab Automation Server Type Library Vm8rQFCp74 3. 将名字改为MLAPP ,bRYqU?#0 <t"KNKI 8bf~uHAr 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 7 ~9Lj b+tm[@|,v 图 编辑/参考 o+%($p C(J+tbk 现在将脚本代码公布如下,此脚本执行如下几个步骤: ZP(T=Q 1. 创建Matlab服务器。 F5s`AjU 2. 移动探测面对于前一聚焦面的位置。 d&owS+B{48 3. 在探测面追迹光线 ~R*01AnZ 4. 在探测面计算照度 xO0}A1t
