    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。 K0H'4' I  
    J@^8ko  
    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: $:cE ^8K  
    enableservice('AutomationServer', true) qOe+ZAJ{%N  
    enableservice('AutomationServer') E.r>7`E  
    c2h{6;bfY  
    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 M2HomO/X)

    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: s:OFVlC%\  
    1. 在FRED脚本编辑界面找到参考. t0/p]=+.p/  
    2. 找到Matlab Automation Server Type Library {\S+#W\  
    3. 将名字改为MLAPP FemC Lvu

    VLS0XKI)  
    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。 z{[xze-f

    2. 移动探测面对于前一聚焦面的位置。 l,R/Gl  
    3. 在探测面追迹光线 /mXBvY  
    4. 在探测面计算照度 Ipf|")*  
    5. 使用PutWorkspaceData发送照度数据到Matlab g'p K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 VGfMN|h  
    7. 用Matlab画出照度数据 |M>eEE*F<  
    8. 在Matlab计算照度平均值 c;%_EN%  
    9. 返回数据到FRED中 {FO;Yg'
