    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。 qg}O/K  
    !Wy[).ZAf  
    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: ]Wq?H-B{  
    enableservice('AutomationServer', true) E)9yH\$6  
    enableservice('AutomationServer') f}@jFhr'<  
    !\,kZ|#>  
    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 ?w+Ix~k  
    N]<!j$pOz  
    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: P7x =  
    1. 在FRED脚本编辑界面找到参考. z ly unJD(  
    2. 找到Matlab Automation Server Type Library wu4NLgkE  
    3. 将名字改为MLAPP m~D&gGFt

    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。 pOrWg@<\L

    现在将脚本代码公布如下,此脚本执行如下几个步骤: j $TwL;  
    1. 创建Matlab服务器。 v,\R, {0  
    2. 移动探测面对于前一聚焦面的位置。 8B#GbS K  
    3. 在探测面追迹光线 !QT'L,_  
    4. 在探测面计算照度 `r_m+]  
    5. 使用PutWorkspaceData发送照度数据到Matlab ??i4z[0M  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v (2GX  
    7. 用Matlab画出照度数据 s9>(Jzcf9

    9. 返回数据到FRED中 ?^EXTU85`"
