    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。 5gP<+S#>T  
    W5'07N^  
    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: J6m`XC  
    enableservice('AutomationServer', true) OPm ?kr  
    enableservice('AutomationServer') VrG4wLpLs  
    P "S=RX#+  
    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 Eu%19s; u  
    #$\cRLPg  
    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: >&uG1q0p.  
    1. 在FRED脚本编辑界面找到参考.  $^&SEz  
    2. 找到Matlab Automation Server Type Library Y-8qAF?SJ]  
    3. 将名字改为MLAPP 6Mpbmfr  
    >;E[XG^  
    i&cH  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 re.%$D@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: E\M{/.4 4  
    1. 创建Matlab服务器。 3YY<2<  
    2. 移动探测面对于前一聚焦面的位置。 \L#BAB6z  
    3. 在探测面追迹光线 3t(8uG<rL  
    4. 在探测面计算照度 q.(p.uD  
    5. 使用PutWorkspaceData发送照度数据到Matlab -KRHcr \  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 nG#lrYZw  
    7. 用Matlab画出照度数据 (xU+Y1*g"%  
    8. 在Matlab计算照度平均值 !$q1m@K1  
    9. 返回数据到FRED中 &`rV{%N"
