    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。 {Kx eH7S  
    3{ LXx  
    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: '_lyoVP  
    enableservice('AutomationServer', true) {0nZ;1,m  
    enableservice('AutomationServer') 9%S{fd\#  
    >XcbNZV  
    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 *p`0dvXG2

    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: HgvgO\`]  
    1. 在FRED脚本编辑界面找到参考. Wb+^Ue  
    2. 找到Matlab Automation Server Type Library l"5$6h  
    3. 将名字改为MLAPP r Lg(J|^  
    K_{f6c<  
    w,bILv)  
    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。 F[<EXLQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?&I gD.  
    1. 创建Matlab服务器。 K{.s{;#  
    2. 移动探测面对于前一聚焦面的位置。 x|d Xa0=N_  
    3. 在探测面追迹光线 LZch7Xe3  
    4. 在探测面计算照度 g]EDL<b  
    5. 使用PutWorkspaceData发送照度数据到Matlab RrSSAoz1  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 KE1S5Mck>  
    7. 用Matlab画出照度数据 6&M $S$y  
    8. 在Matlab计算照度平均值 %jdV8D#Q  
    9. 返回数据到FRED中 ^m;dEe&@F
