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。 aDZ] {; Q Zv}\C-c 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: !"<~n-$B enableservice('AutomationServer', true) w'7=CzfYn enableservice('AutomationServer') _BHEK P9jPdls 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 ki'CW4x 0Ait7` 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: hD9b2KZv 1. 在FRED脚本编辑界面找到参考. *I9O+/, 2. 找到Matlab Automation Server Type Library s"B+),Jod 3. 将名字改为MLAPP 66-G)+4 *=(vIm[KL jH?!\F2)+ 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 {.o@XP,. 9A ?)n<3d 图 编辑/参考 \h5!u1{L 4}F~h 现在将脚本代码公布如下,此脚本执行如下几个步骤: 2(H-q( 1. 创建Matlab服务器。 LsO}a;t5 2. 移动探测面对于前一聚焦面的位置。 '^%k TNn 3. 在探测面追迹光线 aM YtWj 4. 在探测面计算照度 ;"|QW?>$D 5. 使用PutWorkspaceData发送照度数据到Matlab frT<9$QUL 6. 使用PutFullMatrix发送标量场数据到Matlab中 )W*A[c
