    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。 x*:"G'zT  
    Q_k'7Z\g$  
    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: Bv 7os3xb  
    enableservice('AutomationServer', true) &sJ6k/l  
        enableservice('AutomationServer') b>& 3 XDz  
    fV!~SX6S  
    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 @8cn<+"b

    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: *M6j)jqV  
    1. 在FRED脚本编辑界面找到参考. U6YQ*%mZ_  
    2. 找到Matlab Automation Server Type Library tYhNr  
        3. 将名字改为MLAPP tSTl#xy

    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。 h9&0"LHr

    1. 创建Matlab服务器。 h0-CTPQ7A  
    2. 移动探测面对于前一聚焦面的位置。 b C"rQJg  
    3. 在探测面追迹光线 l~x 6R~q  
    4. 在探测面计算照度 Z:VT%-  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6'.CW4L  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 $N4i)>&T2  
    7. 用Matlab画出照度数据 fTi5Ej*/?)  
    8. 在Matlab计算照度平均值 ql_,U8Jw  
    9. 返回数据到FRED中 /Em6+DN>
