    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。 Ha\hQ'99  
    bZJiubBRI  
    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: 0eIR)#j*  
    enableservice('AutomationServer', true) jws(`mIf\  
        enableservice('AutomationServer') )nVx 2m4  
    =cY]cPO  
    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 S([De"y  
    zSO9 U  
    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: p`0Tpgi  
    1. 在FRED脚本编辑界面找到参考. a!.8^:B&  
    2. 找到Matlab Automation Server Type Library !Ai;S  
        3. 将名字改为MLAPP Orgje@c{  
         qKXn=J/0tA  
         vF 1$$7k  
    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。 uNDkK o<M

    3. 在探测面追迹光线 OduTg^R  
    4. 在探测面计算照度 WJWrLu92\U

        6. 使用PutFullMatrix发送标量场数据到Matlab中 Kk#@8h>  
    7. 用Matlab画出照度数据 . j },
