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。
C vtG ZKa.MBde 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:
T!N,1"r enableservice('AutomationServer', true) |JW-P`tL0 enableservice('AutomationServer') niV= Ijt{5 7:t
*&$ 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。 bqAv)2 +LM/< l 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: G6(U\VFqO 1. 在FRED脚本编辑界面找到参考. jz2W/EE`w 2. 找到Matlab Automation Server Type Library %vO b"K$X 3. 将名字改为MLAPP Dh|8$(Jt ApYri|^r :n&n"`D~ 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。 n1xN:A L{\au5-4 图 编辑/参考 @^$Xy<x "7pd(p *C 现在将脚本代码公布如下,此脚本执行如下几个步骤: sC Fqz[I 1. 创建Matlab服务器。 3%<xM/# 2. 移动探测面对于前一聚焦面的位置。 nx >PZb 3. 在探测面追迹光线 ^L(}c O 4. 在探测面计算照度 J!o[/`4ib 5. 使用PutWorkspaceData发送照度数据到Matlab q|.
