    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。 x,=&JtKVc  
    ;km`P|<U  
    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: Bd!bg|uO*  
    enableservice('AutomationServer', true) QyEn pZ8?a  
    enableservice('AutomationServer') /C:Y94B-z  
    v,FU^f-'  
    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 8 }I$'x

    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: [;n9:Qxf  
    1. 在FRED脚本编辑界面找到参考. MU`1LHg  
    2. 找到Matlab Automation Server Type Library R{C(K(5/  
    3. 将名字改为MLAPP k0OYJ/

    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。  L O}@dL

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T;Lkaxsn  
    1. 创建Matlab服务器。 0!4Ts3qn1  
    2. 移动探测面对于前一聚焦面的位置。 H`*LBqDk  
    3. 在探测面追迹光线 3atBX5  
    4. 在探测面计算照度 D#_3^Kiawj  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5#HW2"7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "IZa!eUW  
    7. 用Matlab画出照度数据 xs{3pkTYD  
    8. 在Matlab计算照度平均值 !S$:*5=&  
    9. 返回数据到FRED中 NxkGOAOE
