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。 !%4&O i'bUX=JK 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: B#U:6Ty enableservice('AutomationServer', true) Pe_FW8e#J enableservice('AutomationServer') Ki:.^ g x~fZOF_ 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。 J_PbRb v}AVIdR 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: J< U,~ra\ 1. 在FRED脚本编辑界面找到参考. )2jBhT 2. 找到Matlab Automation Server Type Library *N#{~ 3. 将名字改为MLAPP u9}k^W)E zn@yt%PCV uY6|LTK&x 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。 H(TY. y=)xo7( 图 编辑/参考 Ev7fvz = 5==}8<$ 现在将脚本代码公布如下,此脚本执行如下几个步骤: b\O%gg\p%! 1. 创建Matlab服务器。 M'4$z^@Z 2. 移动探测面对于前一聚焦面的位置。 06#40- 3. 在探测面追迹光线 It/IDPx4ga 4. 在探测面计算照度 x)<Hr,wd 5. 使用PutWorkspaceData发送照度数据到Matlab l6lyRJ 6. 使用PutFullMatrix发送标量场数据到Matlab中 LiF(#OuZ 7. 用Matlab画出照度数据 Y([YDn 8. 在Matlab计算照度平均值 <x|P} 9. 返回数据到FRED中 c$>$2[*= ZOK,P 代码分享: cKKl\g@} 3 O)^Hq+9 Option Explicit QP{V GDW$R`2 Sub Main /=bg(?nX /.u0rxoRP} Dim ana As T_ANALYSIS Do&/+Ssnu Dim move As T_OPERATION 0cwb^ffN Dim Matlab As MLApp.MLApp #&cNR_"w Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long /T_ G9zc Dim raysUsed As Long, nXpx As Long, nYpx As Long [*k25N Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double '!%Zf;Fjr Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double >
