    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。 J!5v~<v?-  
    }=v)Js  
    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: NNF>Xa`9,  
    enableservice('AutomationServer', true) doB  
    enableservice('AutomationServer') /'hCi]b@v  
    |Xw/E)jA  
    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 _ ib"b#  
    nN~~cV  
    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: <&!v1yR  
    1. 在FRED脚本编辑界面找到参考. jr)7kP@  
    2. 找到Matlab Automation Server Type Library r)T:7zy  
    3. 将名字改为MLAPP <HRBMSR+  
    >OP+^^oZ<  
    ;P;((2_X9  
    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。 h1(j2S`:

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5"/J^"!h  
    1. 创建Matlab服务器。 :aG#~-Q  
    2. 移动探测面对于前一聚焦面的位置。 z`Hy'{1  
    3. 在探测面追迹光线 -!)xQvagD.  
    4. 在探测面计算照度 :0/q5_t  
    5. 使用PutWorkspaceData发送照度数据到Matlab .^bft P\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ||zb6|7I4  
    7. 用Matlab画出照度数据 g!i45-n3gt  
    8. 在Matlab计算照度平均值 yi^b)2G  
    9. 返回数据到FRED中 HK~xOAF
