    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。 0(Yh~{   
    $%N;d>[U,  
    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: z(8)1#(n7  
    enableservice('AutomationServer', true) we6+2  
    enableservice('AutomationServer') \ SoYx5lf  
    tuL\7 (R  
    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 ^K1~eb*K

    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: N>W;0u!  
    1. 在FRED脚本编辑界面找到参考. B]+7 JB  
    2. 找到Matlab Automation Server Type Library [u!p-  
    3. 将名字改为MLAPP ]j%*"V

    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。 ~Hp#6+

    1. 创建Matlab服务器。 o>/uW8  
    2. 移动探测面对于前一聚焦面的位置。 r_!{!i3B  
    3. 在探测面追迹光线 MbT ONt?~v  
    4. 在探测面计算照度 *o:B oP=S  
    5. 使用PutWorkspaceData发送照度数据到Matlab |IyM"UH  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8gu'dG=  
    7. 用Matlab画出照度数据 i{1)=_$Vt`  
    8. 在Matlab计算照度平均值 /h}wM6pg  
    9. 返回数据到FRED中 5p#o1I
