    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。 %h}3}p#4  
    \9k{h08s  
    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: ESi-'R&  
    enableservice('AutomationServer', true) ~' q&rvk`  
        enableservice('AutomationServer') k(dNHT  
    <5npVm  
    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 `3L?x8g  
    !Q{~f;L  
    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: LsaRw-4.c  
    1. 在FRED脚本编辑界面找到参考. E[M.q;rM  
    2. 找到Matlab Automation Server Type Library qhOV>j,d  
        3. 将名字改为MLAPP =' &TqiIv"  
         Z[9f8/6<b  
         S<>u  
    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{nDmG`yp

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T^H`$;\  
    1. 创建Matlab服务器。 >/7[HhBT  
    2. 移动探测面对于前一聚焦面的位置。 p1fy)K2{,j  
    3. 在探测面追迹光线 &NK6U  
    4. 在探测面计算照度 rQ&F Gb  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0b+End#mp  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 _Sult;y"u  
    7. 用Matlab画出照度数据 ty b-VO  
    8. 在Matlab计算照度平均值 p/Ri|FD6  
    9. 返回数据到FRED中 I=|}%WO#
