    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。 @su!9]o  
    ;dTxQ_:  
    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: 0KjCM4t  
    enableservice('AutomationServer', true) mBQpf/PG  
    enableservice('AutomationServer') uS! V_]  
    %{0F.  
    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 _!9I f  
    `k(m2k ?  
    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: hbs /S  
    1. 在FRED脚本编辑界面找到参考. `)TgGny01  
    2. 找到Matlab Automation Server Type Library yh.WTgcW  
    3. 将名字改为MLAPP vILgM\or  
    'a"Uw"/p[  
    \xmDkWzE  
    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。 p:3w8#)MZ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {d> 6*b  
    1. 创建Matlab服务器。 Ho $+[K  
    2. 移动探测面对于前一聚焦面的位置。 n D}<zj$D2  
    3. 在探测面追迹光线 t;_1/ mt  
    4. 在探测面计算照度 *E-MJCv  
    5. 使用PutWorkspaceData发送照度数据到Matlab u/FC\xJc  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w{GEWD{&  
    7. 用Matlab画出照度数据 V OT9cP^6  
    8. 在Matlab计算照度平均值 l`a_0  
    9. 返回数据到FRED中 8#HQ05q>
