    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}:Dx  
    Us1@\|]  
    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: Jm?l59bv v  
    enableservice('AutomationServer', true) eT;AAGql  
    enableservice('AutomationServer') ;_x2 Ymw  
    t$aVe"uM  
    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 7 2`/d`

    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: |d5ggf .w  
    1. 在FRED脚本编辑界面找到参考. CP}0Ri)  
    2. 找到Matlab Automation Server Type Library DKR<W.!*t  
    3. 将名字改为MLAPP P~&O4['<  
    Gj6<s./

    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。 yU> T8oFh

    现在将脚本代码公布如下,此脚本执行如下几个步骤: bC6X?m=  
    1. 创建Matlab服务器。 QDP-E[  
    2. 移动探测面对于前一聚焦面的位置。 2%bhW,?I  
    3. 在探测面追迹光线 ,bxz]S1W  
    4. 在探测面计算照度 I`lDWL  
    5. 使用PutWorkspaceData发送照度数据到Matlab SF0Jb"kS  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x 96}#0'  
    7. 用Matlab画出照度数据 bS,etd  
    8. 在Matlab计算照度平均值 r8sdzz%  
    9. 返回数据到FRED中 0xv\D0
