    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。 fyA-*)oHv  
    E3]WRF;l  
    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: Mjy:k|aY"  
    enableservice('AutomationServer', true) mpMAhm:  
        enableservice('AutomationServer') @q q"X'3t  
    p2{7+m  
    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 +ovK~K $A  
    G+t:]\  
    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: @XV&^l -  
    1. 在FRED脚本编辑界面找到参考. pX?3inQP%(  
    2. 找到Matlab Automation Server Type Library a[(OeVQ5  
        3. 将名字改为MLAPP n]ba1t8ZA  
         'in%Gii  
         |uqI}6h.  
    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。 &|~7`

    2. 移动探测面对于前一聚焦面的位置。 AcPLJ!y  
    3. 在探测面追迹光线 2!Dz9m3  
    4. 在探测面计算照度 4JAz{aw'b  
    5. 使用PutWorkspaceData发送照度数据到Matlab :^v Q4/,  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Gl1XRNy C  
    7. 用Matlab画出照度数据 ]VRa4ZB{u
