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。 *Jb_=j*) $!a?i@ 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: R `;o!B}[ enableservice('AutomationServer', true) M} O[`Fx{W enableservice('AutomationServer') 'To<T |xq}'.C 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 pz$_W xttYn]T 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: ha_@Yqgh 1. 在FRED脚本编辑界面找到参考. =fo4x|{O 2. 找到Matlab Automation Server Type Library kfVZ=`p} 3. 将名字改为MLAPP w'd.; Tc:sldtCk q1UBKhpnH 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。 - dl}_ ?#4+r_dP 图 编辑/参考 u/} xE7G `Gf{z%/ 现在将脚本代码公布如下,此脚本执行如下几个步骤: KZECo1 1. 创建Matlab服务器。 !0b%Jh 2. 移动探测面对于前一聚焦面的位置。 =]T|h 3. 在探测面追迹光线 O-Dc[t% 4. 在探测面计算照度 w-lrnjs 5. 使用PutWorkspaceData发送照度数据到Matlab O8gfiQqF& 6. 使用PutFullMatrix发送标量场数据到Matlab中 _=uviMuE 7. 用Matlab画出照度数据 Y]~IY?I 8. 在Matlab计算照度平均值 9 >%+bA( 9. 返回数据到FRED中 1sD~7KPg? 8AryIgy>@ 代码分享: j?( c}!} Bgf=\7;5 Option Explicit VW {,:Ya {-Yee[d<?
