    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。 17+2`@vJgM  
    ,L$, d  
    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: u9D#5NvGs  
    enableservice('AutomationServer', true) rf YFS96  
    enableservice('AutomationServer') fl o9iifZ  
    YxWA] yL  
    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 +K7oyZg

    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: ~JG\b?s  
    1. 在FRED脚本编辑界面找到参考. 5'S~PQka*  
    2. 找到Matlab Automation Server Type Library ev9ltl{  
    3. 将名字改为MLAPP L(DDyA{bA

    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。 N_R(i3c6U!

    2. 移动探测面对于前一聚焦面的位置。 zaG1  
    3. 在探测面追迹光线 8 EUc 6  
    4. 在探测面计算照度 Ms14]M[\  
    5. 使用PutWorkspaceData发送照度数据到Matlab rVv4R/3+   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 }$Z0v`  
    7. 用Matlab画出照度数据 Zx 5Ue#I
