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。 /3,/j)`a [xqV`(vM 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: ZJ3g,dc enableservice('AutomationServer', true) hTDK[4e enableservice('AutomationServer') '|[!I!WB` M=iTwK 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。 z:\9t[e4 Sgi`&;PF 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: n3iiW\ 1. 在FRED脚本编辑界面找到参考. =Dn<DV 2. 找到Matlab Automation Server Type Library -Q20af- 3. 将名字改为MLAPP G^.N$wcv D0Q9A]bD; ^8
VW$} 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。 ,iV%{*p] ?~o`mg 图 编辑/参考 4aHogheg *qzdt^[ xo 现在将脚本代码公布如下,此脚本执行如下几个步骤: >ai,6! 1. 创建Matlab服务器。 {;{U@Z 2. 移动探测面对于前一聚焦面的位置。 VM$n|[C~ 3. 在探测面追迹光线 t'U=K>7 4. 在探测面计算照度 kyHli~Nr" 5. 使用PutWorkspaceData发送照度数据到Matlab ji ?Hw 6. 使用PutFullMatrix发送标量场数据到Matlab中 qHk{5O3 7. 用Matlab画出照度数据 <Z^by;d|z 8. 在Matlab计算照度平均值 PK+sGV 9. 返回数据到FRED中 Uj5-x%~
