    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。 ^4dE8Ve"@  
    cq1 5@a mX  
    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: t#k]K]  
    enableservice('AutomationServer', true) //R"ZE@d\  
    enableservice('AutomationServer') QL?_FwZL  
    A3jxjQ  
    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 BI1M(d#1L"  
    k^J8 p#`6  
    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: IPQRdBQ  
    1. 在FRED脚本编辑界面找到参考. *WwM"NFHDd  
    2. 找到Matlab Automation Server Type Library mMAN* }`O  
    3. 将名字改为MLAPP ?:(y  
    y>I2}P  
    x/*lNG/  
    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。 5S~ H[>A"

    1. 创建Matlab服务器。 l2D*b93  
    2. 移动探测面对于前一聚焦面的位置。 n6/Ous  
    3. 在探测面追迹光线 E }L Hp  
    4. 在探测面计算照度 sPH 2KwEv  
    5. 使用PutWorkspaceData发送照度数据到Matlab >Bt82ibN  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 HI.*xkBXl&  
    7. 用Matlab画出照度数据 u#0snw~)/  
    8. 在Matlab计算照度平均值 ]G/m,Zv*:
