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。 R`5g# A4uKE"WE 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: d6^:lbj enableservice('AutomationServer', true) Sy@)Q[A enableservice('AutomationServer') [g<Y,0,J VdL*"i 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。 f`<elWgc" kz_gR;"(Z 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: *c<6 Er>s 1. 在FRED脚本编辑界面找到参考. ^yLhL^Y 2. 找到Matlab Automation Server Type Library YY zUg 3. 将名字改为MLAPP 2t7P| b~V1 @vZeye =cR"_ Z[8X 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。 D~ogq] Yj CH KI"e 图 编辑/参考 CP'b,}Dd?I -=cxUDB 现在将脚本代码公布如下,此脚本执行如下几个步骤: !n7'TM' 1. 创建Matlab服务器。 y'5`Uo?\", 2. 移动探测面对于前一聚焦面的位置。 TTa$wiW7' 3. 在探测面追迹光线 -1{f(/ 4. 在探测面计算照度 S;0z%$y 5. 使用PutWorkspaceData发送照度数据到Matlab **V8a-@ 6. 使用PutFullMatrix发送标量场数据到Matlab中 Uiv4'vYg 7. 用Matlab画出照度数据 ^GpLl 8. 在Matlab计算照度平均值 O llS 9. 返回数据到FRED中 hp c &s r.q*S4IS.m 代码分享: q4ttmL8 F;bkV}^ Option Explicit AQ&vq$ "T$LJ1E Sub Main u`CHM:<<? 5e3p9K`5 Dim ana As T_ANALYSIS 0QP=$X Dim move As T_OPERATION " Tk, Dim Matlab As MLApp.MLApp Kf-XL),3l Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long ;`O9YbP# Dim raysUsed As Long, nXpx As Long, nYpx As Long Ze!/b|`xI Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double ~GE|,Np Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double h`dHk]O Dim meanVal As Variant 2 g\O/oz uO>x"D5tZ: Set Matlab = CreateObject("Matlab.Application") {,!!jeOO @HzK)%@
