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。 Ejv%,q/T( y,Jh@n';| 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: >-M ]:=L enableservice('AutomationServer', true) f-4.WW2FN enableservice('AutomationServer') P|N2R5(>T jo}1u_OJ 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。 TjxA#D) r4u z} jl{ 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: D?^Y`G$. 1. 在FRED脚本编辑界面找到参考. ^-hEr sK 2. 找到Matlab Automation Server Type Library w]nX?S8 3. 将名字改为MLAPP `z9J`r=I Z0-ytODII obO}NF*g^ 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。 b._m 8z ~ eJHp6)2 图 编辑/参考 kx:jI^ ;$7v%Ls= 现在将脚本代码公布如下,此脚本执行如下几个步骤: 6W&_2a7* 1. 创建Matlab服务器。 =s;M]: 2. 移动探测面对于前一聚焦面的位置。 " !-Kd'V 3. 在探测面追迹光线 Q8q@Y R# 4. 在探测面计算照度 OUI6
