    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。 o*-h%Z.  
    V;H d)v( j  
    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: dFx2>6AZt  
    enableservice('AutomationServer', true) 3Ca \`m)l  
    enableservice('AutomationServer') ^=Q8]W_*  
    wH+FFXGJs  
    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 fE'-.nA+  
    Ft)t`E'%j  
    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: HE*7\"9  
    1. 在FRED脚本编辑界面找到参考. @k_Jl>X  
    2. 找到Matlab Automation Server Type Library } /[_  
    3. 将名字改为MLAPP "3\oQvi.

    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。 1XqIPiXJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :!(YEF#}  
    1. 创建Matlab服务器。 N[0 xqQ  
    2. 移动探测面对于前一聚焦面的位置。 3w t:5 Im  
    3. 在探测面追迹光线  AQB1gzE  
    4. 在探测面计算照度 lTx Y6vi  
    5. 使用PutWorkspaceData发送照度数据到Matlab Tld1P69(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LKIW*M  
    7. 用Matlab画出照度数据 r hiS  
    8. 在Matlab计算照度平均值 D/gd  
    9. 返回数据到FRED中 caGML|DeI
