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。 \.i ejB Uaux0W 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: 7J5jf231 enableservice('AutomationServer', true) klAlS% enableservice('AutomationServer') qonStIP Ru#pJb(R 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。 FIfLDT+ Wh R'tvF$3=i 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: |,`"Omb9+m 1. 在FRED脚本编辑界面找到参考. !:5'MI@ 2. 找到Matlab Automation Server Type Library (_FeX22+ 3. 将名字改为MLAPP $PRd'YdL/ HU/4K7e` z.RM85 ?T 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。 wAW{{ p $Bc3| `K1v 图 编辑/参考 `a[fC9 H1q,w|O9j 现在将脚本代码公布如下,此脚本执行如下几个步骤: <m~8pM 1. 创建Matlab服务器。 Lz_.m 2. 移动探测面对于前一聚焦面的位置。 "2-D[rYZ 3. 在探测面追迹光线 !mqIq}h 4. 在探测面计算照度 2^`k6V! 5. 使用PutWorkspaceData发送照度数据到Matlab ndDF(qHr 6. 使用PutFullMatrix发送标量场数据到Matlab中 ^CQp5k p] 7. 用Matlab画出照度数据 u@:[ dbJ 8. 在Matlab计算照度平均值 gV9bt~ 9. 返回数据到FRED中 2 f%+1uU >#&2 5,Q 代码分享: n05GM.|*s 'lpCwH Option Explicit ct=K.m@E%X x\ #K2 Sub Main X!~y&[;[C PWp=}f.y Dim ana As T_ANALYSIS 2#yDVN$ Dim move As T_OPERATION /DHV-L Dim Matlab As MLApp.MLApp Tr}XG Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long C7W<7DBf Dim raysUsed As Long, nXpx As Long, nYpx As Long ^+d]'$ Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double AFBWiuwI3 Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double P~lU`.X} Dim meanVal As Variant Yc6.v8a 7Q Ns q Set Matlab = CreateObject("Matlab.Application") +Tx_q1/f5X
