    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。 )Be}Ev#)Zx  
    9XF+? x  
    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: {4CkF \  
    enableservice('AutomationServer', true) P`[6IS#\S  
    enableservice('AutomationServer') qOZe\<.V<  
    ]. 1[H~5N  
    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 q{ @>2AlK

    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: dQ`ch~HVUW  
    1. 在FRED脚本编辑界面找到参考. Kx*;!3-V$  
    2. 找到Matlab Automation Server Type Library $"J+3mO  
    3. 将名字改为MLAPP (8@._

    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。 wi:]oo#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :uZcN  
    1. 创建Matlab服务器。 O]m,zk  
    2. 移动探测面对于前一聚焦面的位置。 -} 9ZZ#K  
    3. 在探测面追迹光线 s~]Ri:7~  
    4. 在探测面计算照度  s4;SA  
    5. 使用PutWorkspaceData发送照度数据到Matlab z^{VqC*o+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6T"[M  
    7. 用Matlab画出照度数据 AmRppbj/wO
