    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。 %YefTk8cr,  
    N8:?Z#z  
    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: Oa\!5Pw1  
    enableservice('AutomationServer', true) dsqqq,>Q  
    enableservice('AutomationServer') 4%2QF F @  
    95^w" [}4Q  
    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 <QT u"i  
    a^i`DrX  
    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"W$ZX  
    1. 在FRED脚本编辑界面找到参考. 0wXfu"E{  
    2. 找到Matlab Automation Server Type Library F7UY>z3jL  
    3. 将名字改为MLAPP By6C+)up  
    ?rXh x{vD  
    i>r4Rz!  
    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_{ua0BLDf

    现在将脚本代码公布如下,此脚本执行如下几个步骤: L+bO X  
    1. 创建Matlab服务器。 ULMG"."IH  
    2. 移动探测面对于前一聚焦面的位置。 \ntmD?kA  
    3. 在探测面追迹光线 G+AD &EHV  
    4. 在探测面计算照度 c3&F\3  
    5. 使用PutWorkspaceData发送照度数据到Matlab ja70w:ja  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "Q'#V!  
    7. 用Matlab画出照度数据 u].=b$wHHM  
    8. 在Matlab计算照度平均值 #*#4vMk<  
    9. 返回数据到FRED中 6%C:k,Cx{d
