    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。 @u,+F0Yd  
    Z[Wlyb0  
    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: >G]?  
    enableservice('AutomationServer', true) e#tIk;9Xz  
        enableservice('AutomationServer') @gNpJB]V  
    /:U1!9.y  
    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 _3|6ZO

    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: SU/G)&Mi  
    1. 在FRED脚本编辑界面找到参考. t)LU\!  
    2. 找到Matlab Automation Server Type Library sF y]+DB  
        3. 将名字改为MLAPP DL,[k (  
         Zp`~}LV{  
         Zb]/nP1P  
    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。 bZiyapM

    2. 移动探测面对于前一聚焦面的位置。 oew|23Ytb  
    3. 在探测面追迹光线 A^-iHm  
    4. 在探测面计算照度 <KtBv Ip]  
    5. 使用PutWorkspaceData发送照度数据到Matlab _74UdD{^o  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 R;r|cep  
    7. 用Matlab画出照度数据 KGu= ;  
    8. 在Matlab计算照度平均值 >rKhlUD  
    9. 返回数据到FRED中 ?9p$XG
