    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。 '1>g=Ic0  
    4A\BGD*5  
    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: O ,F]\  
    enableservice('AutomationServer', true) no~OR Q  
    enableservice('AutomationServer') 9 _M H  
    c,v^A+sZu  
    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 =yk Rki  
    &&(4n?   
    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: #~bU}[{  
    1. 在FRED脚本编辑界面找到参考. J8sJ~FnUj  
    2. 找到Matlab Automation Server Type Library SQO>}#qm  
    3. 将名字改为MLAPP LY@1@O2@

    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。 `^X RrVX<

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ImUQ*0  
    1. 创建Matlab服务器。 ?G~/{m.  
    2. 移动探测面对于前一聚焦面的位置。 ZYwBw:y}y  
    3. 在探测面追迹光线 p=8M0k  
    4. 在探测面计算照度 jQ.>2-;H9  
    5. 使用PutWorkspaceData发送照度数据到Matlab )1ZJ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @1pW!AdN  
    7. 用Matlab画出照度数据 [M7iJcwt  
    8. 在Matlab计算照度平均值 rQd1Ch  
    9. 返回数据到FRED中 Jf %!I
