    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。 0p' =Vel{}  
    IH0qx_;P&  
    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: 0 6S-3bis  
    enableservice('AutomationServer', true) Z,m;eCLG]  
    enableservice('AutomationServer') K~Hp%.  
    tV,Y38e  
    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 Q[N6#C:(4  
    RzLbPSTQ  
    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: O(oGRK<xM  
    1. 在FRED脚本编辑界面找到参考. f_GqJ7Gk]  
    2. 找到Matlab Automation Server Type Library Wo+'j $k  
    3. 将名字改为MLAPP cA{zyq26

    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。 Y!|* `FII

    1. 创建Matlab服务器。 [#emm1k  
    2. 移动探测面对于前一聚焦面的位置。 L5tSS=  
    3. 在探测面追迹光线 e$+?l~  
    4. 在探测面计算照度 ^s&1,  
    5. 使用PutWorkspaceData发送照度数据到Matlab  XVKR}I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 2|n~5\K|t  
    7. 用Matlab画出照度数据 I?mU_^no
