    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。 ?r_kyuU  
    3!9 Z=- tD  
    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|2\x  
    enableservice('AutomationServer', true) "cUg>a3  
    enableservice('AutomationServer') Gm8E<iTP  
    rj] E@W  
    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 |hzT;  
     !rL<5L  
    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: dbGgD=}o  
    1. 在FRED脚本编辑界面找到参考. sa-9$},z4  
    2. 找到Matlab Automation Server Type Library 0%C^8%(x  
    3. 将名字改为MLAPP t%0?N<9YkU

    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。 0&w0a P`Y

    1. 创建Matlab服务器。 NP t(MFK \  
    2. 移动探测面对于前一聚焦面的位置。 t 0O4GcAN  
    3. 在探测面追迹光线 4SVW/Zl.?  
    4. 在探测面计算照度 wz(K*FP  
    5. 使用PutWorkspaceData发送照度数据到Matlab |"7Pv skT  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,Qc.;4s-  
    7. 用Matlab画出照度数据 Fz"ff4Bx [
