    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。 V;SfW2`)  
    @yTu/U  
    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: C @Ts\);^  
    enableservice('AutomationServer', true) %KyZ15_(-L  
        enableservice('AutomationServer') JU8}TX  
    db )2>  
    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 ZX_QnSNZ?  
    Q7+WV`&  
    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: 7?fgcb3  
    1. 在FRED脚本编辑界面找到参考. wkt4vE87  
    2. 找到Matlab Automation Server Type Library nDrRK  
        3. 将名字改为MLAPP -h8mJ D%Oi  
         maa pX/J  
         Y9abRr K  
    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。 #(] D]f[@

    1. 创建Matlab服务器。 Jk.x^  
    2. 移动探测面对于前一聚焦面的位置。 i@/%E~W  
    3. 在探测面追迹光线 ?wtKi#k'v#  
    4. 在探测面计算照度 ]y OM  
    5. 使用PutWorkspaceData发送照度数据到Matlab KDN#CU  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 oIrc))j,$  
    7. 用Matlab画出照度数据 kHK<~srB  
    8. 在Matlab计算照度平均值 I(6%'s2  
    9. 返回数据到FRED中 dz#"9i5b
