    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。 AAb3Jf`UW  
    TgoaEufS<  
    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: 3MH9%*w'0  
    enableservice('AutomationServer', true)  LhKaqR{  
    enableservice('AutomationServer') sIJl9  
    5_!s\5  
    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 xf% _HMKc

    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: W US[hx,  
    1. 在FRED脚本编辑界面找到参考. fh,kbn==r?  
    2. 找到Matlab Automation Server Type Library 6#hDj_(,  
    3. 将名字改为MLAPP g 0O~5.f  
    P;4Y%Dq~Qo

    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。 E^qJ5pr_P

    现在将脚本代码公布如下,此脚本执行如下几个步骤: jlXzfD T  
    1. 创建Matlab服务器。 `ECY:3"$KA  
    2. 移动探测面对于前一聚焦面的位置。 RUco3fZ   
    3. 在探测面追迹光线 W T~UEK'  
    4. 在探测面计算照度 Lz6b9W  
    5. 使用PutWorkspaceData发送照度数据到Matlab Pw+PBIGn4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 XB0G7o%1  
    7. 用Matlab画出照度数据 wIQ~a  
    8. 在Matlab计算照度平均值 =>3wI'I  
    9. 返回数据到FRED中 G5A:C(r
