    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。 Oeg^%Y   
    (c3O> *M  
    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: (G>g0(;D-  
    enableservice('AutomationServer', true) |hvclEu,  
    enableservice('AutomationServer') >n&+<06  
    Q`=d5Uvw  
    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 k1D|Cpnp  
    `apCu  
    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: 8X\":l:  
    1. 在FRED脚本编辑界面找到参考. R C!~eJG!  
    2. 找到Matlab Automation Server Type Library o8A(Cg}  
    3. 将名字改为MLAPP "GxQ9=Z  
    tg2+Z\0)4g  
    )4GCL(&  
    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。 w/ID y Q

    l n09_Lr  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8hX /~-H  
    1. 创建Matlab服务器。 \VAS<?3  
    2. 移动探测面对于前一聚焦面的位置。 %wq;<'W  
    3. 在探测面追迹光线 &x[V<Gq  
    4. 在探测面计算照度 -0*z"a9<p8  
    5. 使用PutWorkspaceData发送照度数据到Matlab S]c&T`jx  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^{O1+7d[.  
    7. 用Matlab画出照度数据 ?j8_j  
    8. 在Matlab计算照度平均值 s<LYSrd  
    9. 返回数据到FRED中 t8#u}u
