    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。 tlA4oVII  
    KAO}*?  
    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: /px*v<Aw1  
    enableservice('AutomationServer', true) kS[k*bN0  
    enableservice('AutomationServer') \Llrs-0 M  
    b=Zg1SqV  
    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 |bVNlL"xN  
    plv"/KJM  
    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: f)vD2_E  
    1. 在FRED脚本编辑界面找到参考. U^snb6\5  
    2. 找到Matlab Automation Server Type Library , .x5  
    3. 将名字改为MLAPP ^{zwIH2I]  
    OHR9u  
    "mSDL:$  
    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。 F C2oP,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {o*ziZh  
    1. 创建Matlab服务器。 .1t$(]CyC  
    2. 移动探测面对于前一聚焦面的位置。 Go^W\y   
    3. 在探测面追迹光线 aGr(djD  
    4. 在探测面计算照度 6<(HT#=#  
    5. 使用PutWorkspaceData发送照度数据到Matlab =9LC "eI&|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {MO`0n; rt  
    7. 用Matlab画出照度数据 lF 8B+  
    8. 在Matlab计算照度平均值 v7\~OOoH]  
    9. 返回数据到FRED中 +`yDWN?7
