    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。 .:~{+ <*`  
     LBIsj}e  
    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: K,f"Q<sU%  
    enableservice('AutomationServer', true) JS!`eO/8  
    enableservice('AutomationServer') 7l+:gD  
    Pb] EpyAW  
    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 it.'.aK4  
    } %bP9  
    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: v =]!Po&Q-  
    1. 在FRED脚本编辑界面找到参考. Puq  
    2. 找到Matlab Automation Server Type Library :z^,>So:  
    3. 将名字改为MLAPP Gbwq rH+

    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。 gucgNpX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: F&_b[xso7  
    1. 创建Matlab服务器。 n8.Tag(#  
    2. 移动探测面对于前一聚焦面的位置。 Gl6M(<f\5  
    3. 在探测面追迹光线 -Q MO*PY  
    4. 在探测面计算照度 6 k6}SlN[  
    5. 使用PutWorkspaceData发送照度数据到Matlab DX(!G a  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3 +WmM4|  
    7. 用Matlab画出照度数据 |44 E:pA  
    8. 在Matlab计算照度平均值 B1k;!@@1 4  
    9. 返回数据到FRED中 Koi-b
