    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。 RL*b4 7,  
    Cv;#8Wj}  
    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: VFKFO9  
    enableservice('AutomationServer', true) J|([(  
    enableservice('AutomationServer') TY?O$d2b3  
    v`U;.W  
    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 Hx n#vAc  
    Bve',.xH  
    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: AuY*x;~  
    1. 在FRED脚本编辑界面找到参考. H#G3CD2&  
    2. 找到Matlab Automation Server Type Library ,:0!+1  
    3. 将名字改为MLAPP z`,dEGfh^  
    <`NtTG  
    V`G^Jyj  
    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。 ^?|d< J:{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Z:diM$Z?7  
    1. 创建Matlab服务器。 %AA -G  
    2. 移动探测面对于前一聚焦面的位置。 >O0<u  
    3. 在探测面追迹光线 qKE+,g'  
    4. 在探测面计算照度 m ;wj|@cF  
    5. 使用PutWorkspaceData发送照度数据到Matlab kIRjoKf<F  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 AYDAt5K_  
    7. 用Matlab画出照度数据 VO /b&%  
    8. 在Matlab计算照度平均值 V;gC[7H  
    9. 返回数据到FRED中 }0]iS8*tL
