    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。 \-R\xL  
    ~M LBO  
    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: cg'z:_l  
    enableservice('AutomationServer', true) 3B[u2o>  
        enableservice('AutomationServer') ,ko0XQBl  
    1c}LX.9K  
    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 3C(V<R?

    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: 2M3C 5Fu  
    1. 在FRED脚本编辑界面找到参考. Dh B*k<S  
    2. 找到Matlab Automation Server Type Library udGZ%Mr_  
        3. 将名字改为MLAPP Ue2k^a*Ww

    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。 "y$s`n4Mj

    2. 移动探测面对于前一聚焦面的位置。 iVqXf;eB!5  
    3. 在探测面追迹光线 DyPb]Udb:  
    4. 在探测面计算照度 x]<0Kq9K  
    5. 使用PutWorkspaceData发送照度数据到Matlab &(,-:"{pNR  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 pQ9~^  
    7. 用Matlab画出照度数据 $%0A#&DVh  
    8. 在Matlab计算照度平均值 c-bTf$6}  
    9. 返回数据到FRED中 <<[\ Rv
