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。 qGtXReK rA9BY :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: ;H5H7ezV enableservice('AutomationServer', true) _ukKzY enableservice('AutomationServer') i7:R4G(/# r40#-A$ 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。 bd[zdL#4K :]%z8,6k 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: ar.w'z 1. 在FRED脚本编辑界面找到参考. \ /C-e 2. 找到Matlab Automation Server Type Library gd>Op 3. 将名字改为MLAPP FHVZ/ e WDr'w' m|<j9.iJ 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。 FyN@mX ?pdvFM 图 编辑/参考 OHeVm-VC K9co_n_L 现在将脚本代码公布如下,此脚本执行如下几个步骤: M9{?gM9 1. 创建Matlab服务器。 [xT2c.2__J 2. 移动探测面对于前一聚焦面的位置。 ($^XF: #5 3. 在探测面追迹光线 g_Wf3o857J 4. 在探测面计算照度 a%>p"4WL 5. 使用PutWorkspaceData发送照度数据到Matlab o0Qy?14T- 6. 使用PutFullMatrix发送标量场数据到Matlab中 Pb$ep|`u 7. 用Matlab画出照度数据 -R
