    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。 H~?7 : K  
    f.c2AY~5[  
    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: )m I i.  
    enableservice('AutomationServer', true) h^YUu`P  
    enableservice('AutomationServer') @zJiR{Je-U  
    Jv8VM\ *  
    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 ?jsgBol  
    },;Z<(  
    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: DB0?H+8t  
    1. 在FRED脚本编辑界面找到参考. ^SbxClUfw!  
    2. 找到Matlab Automation Server Type Library >x]ir  
    3. 将名字改为MLAPP Q]]M;(

    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。 `*xSn+wL`_

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4YXp,U  
    1. 创建Matlab服务器。 "$3~):o  
    2. 移动探测面对于前一聚焦面的位置。 ~lbm^S}-  
    3. 在探测面追迹光线 xiVbVr#[  
    4. 在探测面计算照度 TpYdIt9#>  
    5. 使用PutWorkspaceData发送照度数据到Matlab Pk6_1LV  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %r@:7/  
    7. 用Matlab画出照度数据 4 g8t  
    8. 在Matlab计算照度平均值 +E+I.}sOB  
    9. 返回数据到FRED中 U^Iq]L
