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。 ^U,Dx 8cURYg6v 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: 4VC8#x1 enableservice('AutomationServer', true) }n"gX>e~ enableservice('AutomationServer') )Z\Zw~L ln6=XDu 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。 QpS7nGev $)6M@S 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 4sC)hAx&f 1. 在FRED脚本编辑界面找到参考. :H:+XIgoR 2. 找到Matlab Automation Server Type Library TnQW~_: 3. 将名字改为MLAPP Wy /5Qw~s rdAy '38g H%i [; 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 /R>YDout} - "{hP 图 编辑/参考 C+dz0u3s 7d+0'3% 现在将脚本代码公布如下,此脚本执行如下几个步骤: FiXqypT_( 1. 创建Matlab服务器。 Id8e%) 2. 移动探测面对于前一聚焦面的位置。 cu)B!#<!& 3. 在探测面追迹光线 )d|s$l$?7 4. 在探测面计算照度 =CjWPZShV 5. 使用PutWorkspaceData发送照度数据到Matlab 0+.<BOcW5 6. 使用PutFullMatrix发送标量场数据到Matlab中 JcfGe4 7. 用Matlab画出照度数据 J- 5kvQi8 8. 在Matlab计算照度平均值 IfY?P(P 9. 返回数据到FRED中 nEbZ8M ~c*kS E2X 代码分享: `L!L=.}4 Zvra > % Option Explicit u}rJqZ Cj/!m Sub Main u7 <VD O:imX>|u Dim ana As T_ANALYSIS as!P`*@ Dim move As T_OPERATION btbuE Dim Matlab As MLApp.MLApp _3#_6>=M Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long bik lja Dim raysUsed As Long, nXpx As Long, nYpx As Long [*5hx_4%B Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double QB;TQZ Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double >X=V Ph8 Dim meanVal As Variant *<}R=X.
