    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。 dw Aju:-H  
    PiAA,  
    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: {\lu; b!  
    enableservice('AutomationServer', true) KY4|C05 ,  
        enableservice('AutomationServer') #^Sd r-   
    2ht<"  
    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 HjV83S;  
    }$iH 3#E8  
    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: hc~--[1c:  
    1. 在FRED脚本编辑界面找到参考. JH<q7Y6!y  
    2. 找到Matlab Automation Server Type Library PTL52+}/  
        3. 将名字改为MLAPP - n11L  
         bk#u0N  
         HOu<,9?>Q  
    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。 \JN<"/

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1Qf5H!5vx  
    1. 创建Matlab服务器。 #sNa}292"  
    2. 移动探测面对于前一聚焦面的位置。 WWq)Cw R  
    3. 在探测面追迹光线 <\Y>y+$3  
    4. 在探测面计算照度 cWh Aj>?_Q  
    5. 使用PutWorkspaceData发送照度数据到Matlab eFZ`0V0  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 PO |p53  
    7. 用Matlab画出照度数据 oPre$YT}h  
    8. 在Matlab计算照度平均值 Ep?a1&b  
    9. 返回数据到FRED中 0~n= |3*P
