    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。 bNs[O22  
    0b++ 17aV  
    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: {US>)I  
    enableservice('AutomationServer', true) jL_5]pzJ  
    enableservice('AutomationServer') PbEQkjE  
    PL@7 KD Q  
    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 Efr3x{ j  
    !. eAOuq  
    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: o9+Q{|r  
    1. 在FRED脚本编辑界面找到参考. v, 0<9!'v  
    2. 找到Matlab Automation Server Type Library j@t{@Ke  
    3. 将名字改为MLAPP kf K[u/<i  
    hS_.l}0yf  
    w4A#>;Qu*  
    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。 `^e*T'UPl

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4if\5P:j  
    1. 创建Matlab服务器。 UR,?!rJ^B  
    2. 移动探测面对于前一聚焦面的位置。 `oXg<tivU  
    3. 在探测面追迹光线 ^O \q3HA_4  
    4. 在探测面计算照度 A^L?_\e6  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;sQ2 0 B'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O! (85rp/  
    7. 用Matlab画出照度数据 hgwn> p:S#  
    8. 在Matlab计算照度平均值 %omu  
    9. 返回数据到FRED中 g]4y AV<2
