    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。 )"E1/$*k  
    -Gm}i8;  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: #!r>3W&  
    enableservice('AutomationServer', true) VZ9`Kbu  
        enableservice('AutomationServer') =~21.p  
    X7MA>j3m  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 )2:U]d%pk  
    :"Rx$;a  
    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:  4NIb_E0  
    1. 在FRED脚本编辑界面找到参考. #210 Yp#  
    2. 找到Matlab Automation Server Type Library }L^PZS@Jf  
        3. 将名字改为MLAPP G12o?N0p  
         O}6*9Xy  
         "!D,9AkZS  
    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。 /\E3p6\*

    2. 移动探测面对于前一聚焦面的位置。 j& L@L.d  
    3. 在探测面追迹光线 i3$pqNe  
    4. 在探测面计算照度 > V >GiSni  
    5. 使用PutWorkspaceData发送照度数据到Matlab b$`/f:_  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 wiM4,  
    7. 用Matlab画出照度数据 [Z!oVSCZD%  
    8. 在Matlab计算照度平均值 4-C'2?  
    9. 返回数据到FRED中 W/%9=g$m
