    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。 |h,aV(Q  
    uz1t uX_  
    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: &r;4$7  
    enableservice('AutomationServer', true) WBA0! g98  
        enableservice('AutomationServer') V}>0r+NL<  
    EK^ld!g(  
    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 gn? ~y`  
    ~pqp`  
    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: av1*i3  
    1. 在FRED脚本编辑界面找到参考. ba3_5 5]  
    2. 找到Matlab Automation Server Type Library l#,WMu&  
        3. 将名字改为MLAPP Y24: D7Q  
         MOFIR wVZ+  
         ,OLN%2Sq  
    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。 Pv`^#BX'

    2. 移动探测面对于前一聚焦面的位置。 1_7}B4  
    3. 在探测面追迹光线 @Zs}8YhC  
    4. 在探测面计算照度 eD*"#O)W  
    5. 使用PutWorkspaceData发送照度数据到Matlab AG#5_0]P~  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ^z$-NSlI  
    7. 用Matlab画出照度数据 eA>O<Z1>  
    8. 在Matlab计算照度平均值 i%M2(8&^Q
