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。 4E\ntufo 6.s? 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: N%A`rY}u enableservice('AutomationServer', true) :wZ`>,K"t> enableservice('AutomationServer') 5MY}(w F}(QKO* 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。 .00=U;H%` #6sC&w3 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: 4<<bk_7' 1. 在FRED脚本编辑界面找到参考. pptM&Y 2. 找到Matlab Automation Server Type Library |zq!CLjD@ 3. 将名字改为MLAPP ` ]P5, ` u\z!x' !u{"] T: 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。 \41)0,sEy TUUE(sLA 图 编辑/参考 ]p&< nK, AY'?Xt 现在将脚本代码公布如下,此脚本执行如下几个步骤: ),Ho( %T\ 1. 创建Matlab服务器。 A1QI4.K 2. 移动探测面对于前一聚焦面的位置。 QrckTO 3. 在探测面追迹光线 cYM~IA 4. 在探测面计算照度 9jR[:[
