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。 wt_?B_nR ^Yf)lV&[ 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: ^G7n# enableservice('AutomationServer', true) i no7!T` enableservice('AutomationServer') y<'2BTf Z7KB?1{G 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。 V;[__w 2S7H_qo$ 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: 7Dx .; 1. 在FRED脚本编辑界面找到参考. .LGkr@P 2. 找到Matlab Automation Server Type Library >gS5[`xRE 3. 将名字改为MLAPP ]VHdE_7) +i q+ |+$j(YuH 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。 q)z1</B- l+3%%TV@L 图 编辑/参考 ;|2;kvf"w c-3Y SrY 现在将脚本代码公布如下,此脚本执行如下几个步骤: f Dm}J 1. 创建Matlab服务器。 J~yd]L> 2. 移动探测面对于前一聚焦面的位置。 ;03*qOYc 3. 在探测面追迹光线 =%nqMV(y 4. 在探测面计算照度 EiIFVP 5. 使用PutWorkspaceData发送照度数据到Matlab ,uqbS 6. 使用PutFullMatrix发送标量场数据到Matlab中 rTH[?mkf4 7. 用Matlab画出照度数据 m;tY(kO 8. 在Matlab计算照度平均值 9{]r+z: 9. 返回数据到FRED中 Ig?.*j ] vI:bl~ 代码分享: H?/cG_^y0 H $qdU!c Option Explicit 6Kv}2M')+ &oK/]lub Sub Main /iJcy:J J?,!1V= Dim ana As T_ANALYSIS PUFW^"LV Dim move As T_OPERATION exrt|A]_[ Dim Matlab As MLApp.MLApp o"+&^ Dim detNode As Long, detSurfNode As Long, anaSurfNode As Long {$QF*j Dim raysUsed As Long, nXpx As Long, nYpx As Long IG3K Pmu Dim irrad() As Double, imagData() As Double, reals() As Double, imags() As Double %&Q7;?
