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。 JP{Y Q:NF C@b-)In 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: 46[k9T enableservice('AutomationServer', true) ;2N:
=Rv enableservice('AutomationServer') D qu?mg;L a1#",%{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。 iewwL7 $/J4?Wik 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: A9Kt^HR 1. 在FRED脚本编辑界面找到参考. 0fE?(0pBj 2. 找到Matlab Automation Server Type Library Be;l!]i 3. 将名字改为MLAPP yo^M>^P\N Ky[s&>02 tY@+d*u 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 hik.c3 zoibinm}Eg 图 编辑/参考 E\1e8Wyh Fe L !%z 现在将脚本代码公布如下,此脚本执行如下几个步骤: ,eSII2,r4 1. 创建Matlab服务器。 F81Kxcs 2. 移动探测面对于前一聚焦面的位置。 R+r;V ]-/ 3. 在探测面追迹光线 SiLWy=qbR 4. 在探测面计算照度 s.$:.*k 5. 使用PutWorkspaceData发送照度数据到Matlab .C|dGE?, 6. 使用PutFullMatrix发送标量场数据到Matlab中 #KUNZW 7. 用Matlab画出照度数据 Lrjp 8. 在Matlab计算照度平均值 >zX`qv&> 9. 返回数据到FRED中 <IBWA0A=8a A= 96N@m6 代码分享: HC!5AJ&+}v ^^z_[Ih Option Explicit ,8[R0wsBaz +OaBA>Jh9 Sub Main c8h71Cr ovk^ Dim ana As T_ANALYSIS cC pNF `DN Dim move As T_OPERATION "M}3T?0 O Dim Matlab As MLApp.MLApp =xjtPmZ5X Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long eWOZC(I*z Dim raysUsed As Long, nXpx As Long, nYpx As Long K |^OnM Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double w&eq
