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。 ^ @=^;nB &xSa7FY 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: 2j&@p> enableservice('AutomationServer', true) {padD p enableservice('AutomationServer') fnu"*5bE f@V3\Z/6E 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。 XSRdqU>Aun `S/wJ'c 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: `)>7)={ 1. 在FRED脚本编辑界面找到参考. 6vy7l(% 2. 找到Matlab Automation Server Type Library gUax'^w;V; 3. 将名字改为MLAPP )mcEQ -!b /Wj,1WX~ 6L4$vJ 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 X]*QUV]i 3`V1XE.; 图 编辑/参考 j|_E$L A\ HeN~c<NuB 现在将脚本代码公布如下,此脚本执行如下几个步骤: i8pU|VpA 1. 创建Matlab服务器。 '3(l-nPiG^ 2. 移动探测面对于前一聚焦面的位置。 )M<vAUF 3. 在探测面追迹光线 U]4pA#*{| 4. 在探测面计算照度 SAv<& 5. 使用PutWorkspaceData发送照度数据到Matlab JiS5um=(. 6. 使用PutFullMatrix发送标量场数据到Matlab中 34AP(3w 7. 用Matlab画出照度数据 8\ha@&p 8. 在Matlab计算照度平均值 ?/#}ZZK^ 9. 返回数据到FRED中 7S^""*Q^ '` CspY 代码分享: P>QpvSd_# gPC@Yy Option Explicit YE+$H%Jl! ]> !<G8=N Sub Main hZ\+FOx; ug&[ IL~lc Dim ana As T_ANALYSIS Vd9@Dy Dim move As T_OPERATION W 0[N0c Dim Matlab As MLApp.MLApp N+W&NlZ
