    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。 _*wlK;`  
    a@C}0IP)  
    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: yxi*4R  
    enableservice('AutomationServer', true) M'@  
    enableservice('AutomationServer') ].@8/. rg  
    zuJ@@\75  
    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 GFvLd:p` [  
    $,nidK!"  
    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: z7&m,:M  
    1. 在FRED脚本编辑界面找到参考. !fJy7Y  
    2. 找到Matlab Automation Server Type Library X:QRy9]  
    3. 将名字改为MLAPP 4@M`BH`  
    9r 5(  
    Fh}GJE   
    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。 vJ>o9:(6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: UTO$L|K  
    1. 创建Matlab服务器。 jPs{Mr<  
    2. 移动探测面对于前一聚焦面的位置。 u&e?3qKX(  
    3. 在探测面追迹光线 R=S)O.*R  
    4. 在探测面计算照度 u0%bv\$m  
    5. 使用PutWorkspaceData发送照度数据到Matlab ksyQ_4^SO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _TbvQ Y  
    7. 用Matlab画出照度数据 <=%G%V_s  
    8. 在Matlab计算照度平均值 O:#/To'  
    9. 返回数据到FRED中 [f]:h Ji
