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。 u"8 ;fS MLD>"W 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: E%\7Uo- enableservice('AutomationServer', true)
b~Pxgfu" enableservice('AutomationServer') 0.BUfuuh ^Im%D(MY 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。 Rp`_Grcd Wt)SdF=U/ 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: Z(k\J|&9C 1. 在FRED脚本编辑界面找到参考. c<h!QnJ 2. 找到Matlab Automation Server Type Library L^ #< HQ 3. 将名字改为MLAPP 51ajE2+X& )Rhf f$ _z(5e 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。 Ij6Wz.* ss0'GfP 图 编辑/参考 x#j\"$dla nc\C4g 现在将脚本代码公布如下,此脚本执行如下几个步骤: 0nD=|W\@{ 1. 创建Matlab服务器。 bhqq 2. 移动探测面对于前一聚焦面的位置。 N{hF [F 3. 在探测面追迹光线 )_c=mT 4. 在探测面计算照度 Oa\ `; 5. 使用PutWorkspaceData发送照度数据到Matlab A M1C
