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。 ViIt'WX pC2ZN 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: +P:xB0Tm
D enableservice('AutomationServer', true) <5X?6*Qvr enableservice('AutomationServer') Ab ,n^ =NMT H[ 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。 #9M6 q bw\fKZ 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: ZG:#r\a 1. 在FRED脚本编辑界面找到参考. nk|j(D 2. 找到Matlab Automation Server Type Library M0zJGIT~b 3. 将名字改为MLAPP v]SHude{ >{?~cNO& 4=!SG4~o 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。 {|nm0vg`A (hWr!(>C4] 图 编辑/参考 7N9~nEU Ysbd4rN 现在将脚本代码公布如下,此脚本执行如下几个步骤: D;VQoO 1. 创建Matlab服务器。 *5?a%p 2. 移动探测面对于前一聚焦面的位置。 A(zF[\{] 3. 在探测面追迹光线 Yt*2/jw^ 4. 在探测面计算照度 K(@QKRZ7[ 5. 使用PutWorkspaceData发送照度数据到Matlab XJ,P8nx 6. 使用PutFullMatrix发送标量场数据到Matlab中 ^L#\z7 7. 用Matlab画出照度数据 ~'>RK 8. 在Matlab计算照度平均值 `]%\Y>(a} 9. 返回数据到FRED中 4gbi?UAmX [-C-+jC 代码分享: erTb9`N4 GO0Spf_Gh Option Explicit |TM&:4D]^ \9k$pC+l Sub Main Rj6:.KEJ 9ZFvN*Zf' Dim ana As T_ANALYSIS hd{Vz{;W Dim move As T_OPERATION 7yp7`|,p Dim Matlab As MLApp.MLApp B^g+_; Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long _%^t[4)q Dim raysUsed As Long, nXpx As Long, nYpx As Long C/V{&/5w Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double rw_T&>!
