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。 iB99.,o-& [1GwcXr 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: C}9GrIi enableservice('AutomationServer', true) kjQW9QJ< enableservice('AutomationServer') N_Ezp68Fp xi"ff. 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。 z}}P+P/ {KDN|o+% 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: I[rR-4.F] 1. 在FRED脚本编辑界面找到参考. /7#MJH5b6 2. 找到Matlab Automation Server Type Library 6RIbsy 3. 将名字改为MLAPP Qu<6X@+5 AP z"k?D0 l4mRNYv)z 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。 ZweAY.]e jD<xpD 图 编辑/参考 ta5_k&3N =x?WZMO 现在将脚本代码公布如下,此脚本执行如下几个步骤: .[eC w 1. 创建Matlab服务器。 S/*\j7cj 2. 移动探测面对于前一聚焦面的位置。 bGB$a0 3. 在探测面追迹光线 XXm7rn 4. 在探测面计算照度 h+Lpj^<2a 5. 使用PutWorkspaceData发送照度数据到Matlab ^?]-Q*w3Qs 6. 使用PutFullMatrix发送标量场数据到Matlab中 q%M~gp1 7. 用Matlab画出照度数据 P )oNNY6} 8. 在Matlab计算照度平均值 AJ}m2EH 9. 返回数据到FRED中 ~u!V_su]GY IlO,Ql 代码分享: 0N)DHD?U vaQsG6q[ Option Explicit xC5Pv"> Mb"y{Fox Sub Main '>"blfix8 % u VTf Dim ana As T_ANALYSIS Y6Y"fb%K Dim move As T_OPERATION Q)XH5C2X Dim Matlab As MLApp.MLApp iEI#J!~ Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long atd;)o0*0 Dim raysUsed As Long, nXpx As Long, nYpx As Long mw^>dv?
