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。 D8B\F5..c# Rq",;,0ZJ 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: #ax% n enableservice('AutomationServer', true) /18fpH| enableservice('AutomationServer') &{wRB l #
\%]lsml 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。 .!2
u#A I:al[V2g 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: o9Mr7 1. 在FRED脚本编辑界面找到参考. -y_q 2. 找到Matlab Automation Server Type Library wr:-n 3. 将名字改为MLAPP jC>mDnX #U3q
+d+^ N`X|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。 vz:VegS _~>WAm< 图 编辑/参考 cFjD*r- |,TBP@ 现在将脚本代码公布如下,此脚本执行如下几个步骤: |Q%nnN 1. 创建Matlab服务器。 ?hp,h3s;n$ 2. 移动探测面对于前一聚焦面的位置。 cj2^wmkB 3. 在探测面追迹光线 1B 0[dK2N 4. 在探测面计算照度 /UR;,ts 5. 使用PutWorkspaceData发送照度数据到Matlab !w!k0z] 6. 使用PutFullMatrix发送标量场数据到Matlab中 wJgH15oB 7. 用Matlab画出照度数据 !-SI &qy 8. 在Matlab计算照度平均值 S5L0[SZ$! 9. 返回数据到FRED中 tk 5p@l cV`NQt <W 代码分享: @b5$WKPX L"T :#> Option Explicit c&<Ei1 >G [:Q
