    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。 v6|RJt?  
    zxEL+P  
    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: pt?bWyKG  
    enableservice('AutomationServer', true) 3s*mbk[J  
        enableservice('AutomationServer') ,.S~ Y  
    />C^WQI^  
    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 ]IaMp788  
    vo?9(+:|e  
    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: cUk7i`M;6  
    1. 在FRED脚本编辑界面找到参考. v{RZJ^1  
    2. 找到Matlab Automation Server Type Library 1> ?M>vK  
        3. 将名字改为MLAPP #x@$ lc=k3  
         UJUEYG  
         , };& tR  
    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。 ]U?^hZ_

    现在将脚本代码公布如下,此脚本执行如下几个步骤: _IMW {

    2. 移动探测面对于前一聚焦面的位置。 'B$yo]  
    3. 在探测面追迹光线 kb%;=t2  
    4. 在探测面计算照度 q$L%36u~/  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7jrt7[{  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 T}Tp$.gB  
    7. 用Matlab画出照度数据 85= )lu  
    8. 在Matlab计算照度平均值 |o"?gB}Dh
