    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。 @}oY6cW;B*  
    Jjr&+Q^3Tu  
    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: +;|" #  
    enableservice('AutomationServer', true) YK V?I   
    enableservice('AutomationServer') \}p!S$`  
    O`rKxP  
    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 t)__J\xF

    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: oz[Mt i*  
    1. 在FRED脚本编辑界面找到参考. !*1Kjg3  
    2. 找到Matlab Automation Server Type Library z=[?&X]O9b  
    3. 将名字改为MLAPP )a=58r07

    ,Qb(uirl]  
    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。 PZ[hH(EX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9V0@!M8S  
    1. 创建Matlab服务器。 xro%AM  
    2. 移动探测面对于前一聚焦面的位置。 ,VYUQE>\  
    3. 在探测面追迹光线 w40 -K5wt>  
    4. 在探测面计算照度 hziPHuK9,  
    5. 使用PutWorkspaceData发送照度数据到Matlab $eU oFa5A  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 5z=.Z\M`8  
    7. 用Matlab画出照度数据 p2I9t|  
    8. 在Matlab计算照度平均值 +v{g'  
    9. 返回数据到FRED中 M7PG s-l
