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。 3z5w}qN]M a$-:F$z 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: zI1-l9 o enableservice('AutomationServer', true) Y_S>S(0 enableservice('AutomationServer') AT$eTZ]M !A@Ft}FB 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 @'XxMO[Z!< ':Avh|q3N 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: lM/)<I\8 1. 在FRED脚本编辑界面找到参考. b9FfDDOq" 2. 找到Matlab Automation Server Type Library u6tD5Y 3. 将名字改为MLAPP L!2BE[~ /-J12 O zPWJ=T@N 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 k?[|8H~2C 1j4(/A 图 编辑/参考 Vm+e% J)yNp,V 现在将脚本代码公布如下,此脚本执行如下几个步骤: =\u QGH 1. 创建Matlab服务器。 OZ,%T9vP 2. 移动探测面对于前一聚焦面的位置。 \l$gcFXb 3. 在探测面追迹光线 5ctH=t0 4. 在探测面计算照度 [3&Y* W 5. 使用PutWorkspaceData发送照度数据到Matlab LNm{}VJ% 6. 使用PutFullMatrix发送标量场数据到Matlab中 YhpNeP{A 7. 用Matlab画出照度数据 [,_4#Zz 8. 在Matlab计算照度平均值 wlvh DJ 9. 返回数据到FRED中 J^" 9#C hn~ \ 代码分享: F^knlv' O:K={#Xj Option Explicit <Vu/6"DP /1s|FI$-L Sub Main _@-D/g fYv= yP~ Dim ana As T_ANALYSIS UM?{ba9 Dim move As T_OPERATION 0H<&*U_V Dim Matlab As MLApp.MLApp %(72+B70R Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long UBN^dbP* Dim raysUsed As Long, nXpx As Long, nYpx As Long gtizgUS7 Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double u>e4;f`F Dim z As Double, xMin As Double, xMax As Double, yMin As Double, yMax As Double F%<hng%k Dim meanVal As Variant )}{V#,xz@ *C>B-j$ Set Matlab = CreateObject("Matlab.Application") H?ZlJ|/c ,sU#{.( ClearOutputWindow Y%1J[W Cq-d, 'Find the node numbers for the entities being used. z@\r V@W5 detNode = FindFullName("Geometry.Screen") =SY5E{`4p detSurfNode = FindFullName("Geometry.Screen.Surf 1") '%k<? * anaSurfNode = FindFullName("Analysis Surface(s).Analysis 1") ^Md]e<WAp i Eh
