    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。 8<KC-|y.  
    Ge=\IAj  
    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: "{3|(Qs  
    enableservice('AutomationServer', true) {a9.0N:4  
    enableservice('AutomationServer') Tu,nX'q]m  
    ~Ga{=OM??  
    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 4!-R&<TLve

    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: `krVfE;_O  
    1. 在FRED脚本编辑界面找到参考. !YlEXaS  
    2. 找到Matlab Automation Server Type Library ?P#\ CW  
    3. 将名字改为MLAPP (Kg)cc[B`  
    7 n^1H[q  
    n!lE|if  
    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。 npbf>n^R

    1. 创建Matlab服务器。 w vI v+Q9  
    2. 移动探测面对于前一聚焦面的位置。 P=9UK`n  
    3. 在探测面追迹光线 0m\( @2E  
    4. 在探测面计算照度 /+. m.TF  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^EW6}oj[  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 f 9IqcCSW  
    7. 用Matlab画出照度数据 osLEH?iKW  
    8. 在Matlab计算照度平均值 |<y1<O>F  
    9. 返回数据到FRED中 /Bk`3~]E>
