    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。 _3yG<'f[Y  
    A8*zB=C  
    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: S* O. ?  
    enableservice('AutomationServer', true) ZDbe]9#Xh  
    enableservice('AutomationServer') *Z_4bR4Q  
    -HQbvXAS  
    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\5|

    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: z77>W}d  
    1. 在FRED脚本编辑界面找到参考. ]{\ttb%GX  
    2. 找到Matlab Automation Server Type Library Gb\PubJ  
    3. 将名字改为MLAPP qz>R"pj0g  
    .Lna\Bv  
    /~{`!30  
    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。 +lqGf

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ebQgk Y=  
    1. 创建Matlab服务器。 oIj=ba(n1  
    2. 移动探测面对于前一聚焦面的位置。 A!B.+p[ G  
    3. 在探测面追迹光线 p|ink):  
    4. 在探测面计算照度 ?e<2'\5v  
    5. 使用PutWorkspaceData发送照度数据到Matlab LsuOmB|^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 N8dxgh!,  
    7. 用Matlab画出照度数据 yQ N{)rv  
    8. 在Matlab计算照度平均值 UE.kR+1  
    9. 返回数据到FRED中 _o$jk8jOjW
