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。 Rd5ni2-nve CPq{M.B 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: r`]&{0}23 enableservice('AutomationServer', true) KlgPDV9mg enableservice('AutomationServer') ; 6Wlu3I W~GbB:- 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。 } d /5_X Xtqjx@ye 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: Wxl^f?I`: 1. 在FRED脚本编辑界面找到参考. !g /&ws& 2. 找到Matlab Automation Server Type Library U;n$ 3. 将名字改为MLAPP u,0N[.&N Hz$l)g}U 1xM'5C?~7 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 ag^L' h$ N9r}nqCN 图 编辑/参考 -bHQy: .3Nd[+[ 现在将脚本代码公布如下,此脚本执行如下几个步骤: >:M3!6H_~{ 1. 创建Matlab服务器。 f[3DKA 2. 移动探测面对于前一聚焦面的位置。 Evkb`dU3n 3. 在探测面追迹光线 I]P'wav~O 4. 在探测面计算照度 <Vyv)#32o3 5. 使用PutWorkspaceData发送照度数据到Matlab C=ni5R 6. 使用PutFullMatrix发送标量场数据到Matlab中 W)jO 4,eO 7. 用Matlab画出照度数据 c[]_gUp8 8. 在Matlab计算照度平均值 U'S}7gya 9. 返回数据到FRED中 3jPua)=p TEl:;4 代码分享: ][-N< vCT5do"C& Option Explicit edhNQWn +MPM^ m Sub Main Dt)\q^bH) AOQimjW9a Dim ana As T_ANALYSIS 2?ac\c6" Dim move As T_OPERATION 6V\YYrUz Dim Matlab As MLApp.MLApp KE:PRX Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long V|b9zHh Dim raysUsed As Long, nXpx As Long, nYpx As Long +8 5]]}I Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double n'=-bj` Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double a'f"Zdh%w Dim meanVal As Variant 6lO]V=+ LY2oBX@fC Set Matlab = CreateObject("Matlab.Application") Yu-e|: :#58m0YLA: ClearOutputWindow 5bM/
