    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。 wl #Bv,xf  
    cq+|fg~Yy  
    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: m!5P5U x  
    enableservice('AutomationServer', true) &U ]L@ ]x  
    enableservice('AutomationServer') x?Doe`/6?  
    f/RzE  
    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 R9nW5f Nf  
    yB\}e'J^  
    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: Tz3 L#0:j  
    1. 在FRED脚本编辑界面找到参考. 0gw0  
    2. 找到Matlab Automation Server Type Library :@{(^}N8u  
    3. 将名字改为MLAPP  fy" q  
    DZ -5A  
    FuiG=quY  
    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。 St9W{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4Ei*\:  
    1. 创建Matlab服务器。 V  @8+  
    2. 移动探测面对于前一聚焦面的位置。 8R"c}87  
    3. 在探测面追迹光线 >%5Ld`c:SD  
    4. 在探测面计算照度 G=Hvh=K(  
    5. 使用PutWorkspaceData发送照度数据到Matlab E|Mu1I]e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3 ha^NjE  
    7. 用Matlab画出照度数据 fVx<f.xuW  
    8. 在Matlab计算照度平均值 ;rZR9fR  
    9. 返回数据到FRED中 Aon 3G
