    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。 i'eYmm96Q  
    f4 Sw,A  
    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: "-~D! {rS  
    enableservice('AutomationServer', true) 0+VncL)u  
    enableservice('AutomationServer') ~T;a jvJ  
    #*ZnA,  
    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 6T} CPDRq

    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: )%H5iSNG$P  
    1. 在FRED脚本编辑界面找到参考. os "[Iji  
    2. 找到Matlab Automation Server Type Library Jq$6$A,f  
    3. 将名字改为MLAPP j? Jd@(*y$

    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。 .:|#9%5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Fw_bY/WN{  
    1. 创建Matlab服务器。 / %U~lr  
    2. 移动探测面对于前一聚焦面的位置。 @wAr[.lZ  
    3. 在探测面追迹光线 s[{:>~{iq  
    4. 在探测面计算照度  q~:'R  
    5. 使用PutWorkspaceData发送照度数据到Matlab N('S2yfDR  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 RT_Pd\(qD  
    7. 用Matlab画出照度数据 "0!eb3n  
    8. 在Matlab计算照度平均值 hK9t}NE.O  
    9. 返回数据到FRED中 Xdp`Z'g
