    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。 UMN*]_'+;b  
     st 'D  
    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: =xianQ<lK  
    enableservice('AutomationServer', true) t_ur&.^SB  
        enableservice('AutomationServer') 4Tct  
    &2I*0  
    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 _DP|-bp D  
    iK_c.b  
    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: Ejq#~Zhr!  
    1. 在FRED脚本编辑界面找到参考. k#:2'!7G  
    2. 找到Matlab Automation Server Type Library "gW7<ilw  
        3. 将名字改为MLAPP ;o<m}bGaT  
         W >(vYU  
         ->lu#; A5  
    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。 fYrGpW( `

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /\Q*MLwD  
    1. 创建Matlab服务器。 lnbmoHv

    3. 在探测面追迹光线 qO`qJ/  
    4. 在探测面计算照度 xeTgV&$@  
    5. 使用PutWorkspaceData发送照度数据到Matlab v$w++3H  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 "zZI S6j
