    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。 qTGEi  
    01 UEd8  
    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: *2$I, ~(P  
    enableservice('AutomationServer', true) "F,d}3}  
        enableservice('AutomationServer') d"7l<y5  
    C2 ~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 h^u 9W7.

    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: 3EM=6\#q  
    1. 在FRED脚本编辑界面找到参考. 3Pb]Of#  
    2. 找到Matlab Automation Server Type Library \xQ10\u  
        3. 将名字改为MLAPP M.h)]S>

         |"7^9(  
    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。 qyfw$$X

    2. 移动探测面对于前一聚焦面的位置。 B&tU~  
    3. 在探测面追迹光线 0a#2 Lo  
    4. 在探测面计算照度 t-xw=&!w  
    5. 使用PutWorkspaceData发送照度数据到Matlab hkS K;  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 *?k~n9n5U  
    7. 用Matlab画出照度数据 Lyx \s;  
    8. 在Matlab计算照度平均值 :/Zy=F9:
