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。 *ax$R6a#X {|bf` 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: <Zl}u:(w enableservice('AutomationServer', true) ~+7q.XL$$K enableservice('AutomationServer') #zyEN+ ESft:3xyw 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。 +g>)Bur a)/!ifJ; 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: 0ERA(=w5 1. 在FRED脚本编辑界面找到参考. ~A(fn:d 2. 找到Matlab Automation Server Type Library l`4hWs\I 3. 将名字改为MLAPP _f8Wa u# " p<: bPw R#DnV[!\ 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。 '1_CMr \ym3YwP4/: 图 编辑/参考 |9Q4VY'"; sEm-Td+A5 现在将脚本代码公布如下,此脚本执行如下几个步骤: R<I)}<g(A3 1. 创建Matlab服务器。 j|c 2. 移动探测面对于前一聚焦面的位置。 &A)AV<=>T 3. 在探测面追迹光线 8GgZAu'X 4. 在探测面计算照度 h(l4\) 5. 使用PutWorkspaceData发送照度数据到Matlab 5ro^<P0f** 6. 使用PutFullMatrix发送标量场数据到Matlab中 W_8N?coM 7. 用Matlab画出照度数据 SvLI%>B=9 8. 在Matlab计算照度平均值 $F"'=+0 9. 返回数据到FRED中 bz <f u y@Z@ eK3 代码分享: 50q(8F-N ZF^$?;'3 Option Explicit Q'>pOtJG*J f~
