    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。 SXm Hn.?  
    gye'_AR?k  
    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@1g=q  
    enableservice('AutomationServer', true) %DF-;M"8  
        enableservice('AutomationServer') a2`|6M;  
     N'e3<  
    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}>#s3KPA

    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: Oxhc!9F  
    1. 在FRED脚本编辑界面找到参考. 94xRKQ}  
    2. 找到Matlab Automation Server Type Library N\WEp?%~  
        3. 将名字改为MLAPP o+.LG($+U  
         w%Tjn^d  
         *we*IhIP  
    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。 DAtZp%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: BjyGk+A   
    1. 创建Matlab服务器。 Z4'8x h)-  
    2. 移动探测面对于前一聚焦面的位置。 |oI]  
    3. 在探测面追迹光线 %Ut7%obpi  
    4. 在探测面计算照度 2n8spLZYGY  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;p4|M  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ;/]v mgl2  
    7. 用Matlab画出照度数据 g4 G?hv`R  
    8. 在Matlab计算照度平均值 \z>L,U  
    9. 返回数据到FRED中 q_ |YLs`
