    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。 4@{;z4*`  
    $O|Xq7dp  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: H k}P  
    enableservice('AutomationServer', true) Ftyxz&-4$p  
    enableservice('AutomationServer') <aPZE6z  
    {QEvc  
    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 L'wR$  
    %w&+o.k/  
    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: 4rhHvp  
    1. 在FRED脚本编辑界面找到参考. 4-bM90&1t  
    2. 找到Matlab Automation Server Type Library l"J#Pvi  
    3. 将名字改为MLAPP nAQ[ -NbW,  
     ]! ZZRe  
    (Nzh1ul\}  
    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。 ,zjz "7'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 61_PSScSY  
    1. 创建Matlab服务器。 IR"C?  
    2. 移动探测面对于前一聚焦面的位置。 `C4(C4u  
    3. 在探测面追迹光线 <8(q.  
    4. 在探测面计算照度 Q%6zr9  
    5. 使用PutWorkspaceData发送照度数据到Matlab _#~D{91 j:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Da<`| l  
    7. 用Matlab画出照度数据 Af\@J6viF7  
    8. 在Matlab计算照度平均值 5B%KiE&p  
    9. 返回数据到FRED中 fhg'4FO
