    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。 b8glZb*$  
    W"&,=wvg2  
    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: "NTiQ}i  
    enableservice('AutomationServer', true) 6!wk5#  
    enableservice('AutomationServer') >+):eB L  
    ]AX3ov6z9;  
    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 ~nApRC)0  
    S:1g(f*85  
    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:  BO.Db``  
    1. 在FRED脚本编辑界面找到参考. 0B: v0 R  
    2. 找到Matlab Automation Server Type Library - B?c F9  
    3. 将名字改为MLAPP :TkMS8  
    S q{@4F}d  
    DKF '*  
    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。 %^[D+1ULb

    现在将脚本代码公布如下,此脚本执行如下几个步骤: jwP5pu  
    1. 创建Matlab服务器。 %*#+(A"V  
    2. 移动探测面对于前一聚焦面的位置。 >T-4!ZvS\j  
    3. 在探测面追迹光线 1x%B`d  
    4. 在探测面计算照度 ',/2J0_  
    5. 使用PutWorkspaceData发送照度数据到Matlab cZ#%tT#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 L @Q+HN  
    7. 用Matlab画出照度数据 nu(7Y YCM$  
    8. 在Matlab计算照度平均值 rR 86D  
    9. 返回数据到FRED中 bP>Kx-%q
