    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。 EN m%(G$  
    %.Y5%T yP  
    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: $dfc@Fn^x  
    enableservice('AutomationServer', true) !y_FbJ8KC  
    enableservice('AutomationServer') a4:GGzt  
    <4rnOQ:  
    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 |E+.y&0;

    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: i{$-[*WHiV  
    1. 在FRED脚本编辑界面找到参考. V?XQjH1X  
    2. 找到Matlab Automation Server Type Library TdFU,  
    3. 将名字改为MLAPP ^0]0ss;##R

    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。 !MoAga_ j

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3IYFvq~  
    1. 创建Matlab服务器。 rHKO13WF  
    2. 移动探测面对于前一聚焦面的位置。 .x I Aep_  
    3. 在探测面追迹光线 aRTy=~  
    4. 在探测面计算照度 JrcbJt  
    5. 使用PutWorkspaceData发送照度数据到Matlab O Z ./suR)  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  Bx45yaT  
    7. 用Matlab画出照度数据 Fz#@[1,  
    8. 在Matlab计算照度平均值 /8; m.J>bf  
    9. 返回数据到FRED中 '$FF/|{
