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。 _jU5O; eW'2AT?2H% 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: *u6Y8IL1 enableservice('AutomationServer', true) /t<@"BoV enableservice('AutomationServer') TJ8E"t*) gR^>3n' 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。 [%A4]QzWh ]q5`YB%_ 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: 4\ c,)U} 1. 在FRED脚本编辑界面找到参考. \VMD$zZx 2. 找到Matlab Automation Server Type Library e?0q9W 3. 将名字改为MLAPP 1SIq[1 #L}+H!Myh lfsqC};#\ 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。 3oZ=k]\ qZEoiNH(Tj 图 编辑/参考 S"m cUU}} 9i5,2~ 现在将脚本代码公布如下,此脚本执行如下几个步骤: 3-Dt[0%{ 1. 创建Matlab服务器。 69y;`15 2. 移动探测面对于前一聚焦面的位置。 A=zPLq{Sb 3. 在探测面追迹光线 M]v=- 4. 在探测面计算照度 x"P);su 5. 使用PutWorkspaceData发送照度数据到Matlab |WryBzZ>on 6. 使用PutFullMatrix发送标量场数据到Matlab中 DHC+C4 7. 用Matlab画出照度数据 C`jM0Q 8. 在Matlab计算照度平均值 X6+qpp 9. 返回数据到FRED中 _M[,!{ C Qcjc, 代码分享: ^-CINt{O cV{%^0?D Option Explicit J/!cGr(B~ h4pTq[4* Sub Main }U w&Ny J~B
