    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。 cnL@j_mb  
    i*6 1i0  
    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: QI4a@WB]ok  
    enableservice('AutomationServer', true) [pzo[0G 'v  
    enableservice('AutomationServer') czcsXBl[  
    {(5M)|>  
    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 >jRH<|Az  
    `ZPV.u/  
    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: um=qT)/D  
    1. 在FRED脚本编辑界面找到参考. ? oQ_qleuo  
    2. 找到Matlab Automation Server Type Library &eFv~9  
    3. 将名字改为MLAPP {SwvUWOf"

    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。 i{MzQE+_^

    1. 创建Matlab服务器。 3h4'DQ.g  
    2. 移动探测面对于前一聚焦面的位置。 87OX:6  
    3. 在探测面追迹光线 ~+anI  
    4. 在探测面计算照度 7NP Ny  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8?[#\KgH1  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =`f"8 ,5  
    7. 用Matlab画出照度数据 lQt* LWd[

    9. 返回数据到FRED中 I`[s(C>3@
