    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。 3sH\1)Zz  
    aF!Ex  
    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: 'T\dkSJv;V  
    enableservice('AutomationServer', true) i+g~ Uj}h  
        enableservice('AutomationServer') ]eE 1n2  
    '"y}#h__T  
    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 M\Se_  
    ;HDZ+B  
    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: ebqg"tPN{  
    1. 在FRED脚本编辑界面找到参考. MDJc[am  
    2. 找到Matlab Automation Server Type Library &VDl/qnaL  
        3. 将名字改为MLAPP >c<pDNt?  
         i[\w%(83Fi  
         >OV<_(S4  
    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。 `ncNEHh7K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: SxJ$b  
    1. 创建Matlab服务器。 nZfs=@w:y  
    2. 移动探测面对于前一聚焦面的位置。 sYJL-2JX  
    3. 在探测面追迹光线 .u l 53 m  
    4. 在探测面计算照度 `H\)e%]  
    5. 使用PutWorkspaceData发送照度数据到Matlab &iNwvA%9D  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 >!L&>OOx  
    7. 用Matlab画出照度数据 CK0l9#g  
    8. 在Matlab计算照度平均值 .wmnnvtl,  
    9. 返回数据到FRED中 K/txD20 O|
