    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。 Om1z  
    ~IWi @m{  
    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: bL[PNUG  
    enableservice('AutomationServer', true) R&alq  
    enableservice('AutomationServer') <s7{6n')  
    I] "$h]T  
    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 1)PR]s:-m@  
    z~Pmh%b  
    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:  #b"IX`5  
    1. 在FRED脚本编辑界面找到参考. R$3JbR.  
    2. 找到Matlab Automation Server Type Library *HXq`B  
    3. 将名字改为MLAPP Q)}\4&4  
    /1>  
    V[bc-m  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 q}1$OsM

    %5KR}NXX6  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: [qI*]  
    1. 创建Matlab服务器。 V_1#7  
    2. 移动探测面对于前一聚焦面的位置。 qlxW@|  
    3. 在探测面追迹光线 uHIWbF<0oo  
    4. 在探测面计算照度 D8#q.OR]  
    5. 使用PutWorkspaceData发送照度数据到Matlab =!c+|X`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 0*"j:V  
    7. 用Matlab画出照度数据 0l6djN  
    8. 在Matlab计算照度平均值 cU6#^PFu  
    9. 返回数据到FRED中 [uY 2N h
