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。 dDpe$N uN$X3Ls_ 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: <[~x]- enableservice('AutomationServer', true) vO0ql enableservice('AutomationServer') t Ac;O[L Q 5@~0 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。 "r"Y9KODm hJd#Gc~*M 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: sXhtn'<v 1. 在FRED脚本编辑界面找到参考. }Bc6:a 2. 找到Matlab Automation Server Type Library c&0IJ7fZG 3. 将名字改为MLAPP 5lU`o 6eS#L2 1* B1LnuB% 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。 r`S]`&#}( hlUF9} 图 编辑/参考 bM-Y4[ @Rx/]wyH 现在将脚本代码公布如下,此脚本执行如下几个步骤: ?<nz2 piP, 1. 创建Matlab服务器。 "%.#/!RG 2. 移动探测面对于前一聚焦面的位置。 .IKK.G 3. 在探测面追迹光线 *E$D, 4. 在探测面计算照度 p O:
