    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。 /cdLMm:  
    $H3C/|  
    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: 1yF9zKs&_  
    enableservice('AutomationServer', true) H74'I}  
    enableservice('AutomationServer') 0&NM=~  
    q7aqbkwz}  
    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 V}<<?_

    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: X$u l=iBs  
    1. 在FRED脚本编辑界面找到参考. S9l po_!z  
    2. 找到Matlab Automation Server Type Library @6DKw;Q  
    3. 将名字改为MLAPP lrHN6:x(Y4  
    Ag:/iB ]  
    K'8?%&IQ  
    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。 .yUD\ZGJ u

    1. 创建Matlab服务器。 g$)0E<  
    2. 移动探测面对于前一聚焦面的位置。 Tg@G-6u0c  
    3. 在探测面追迹光线 #+6j-^<_6  
    4. 在探测面计算照度 M-Vz$D/aed  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;6 d-+(@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x%$6l  
    7. 用Matlab画出照度数据 ^=-25%&^  
    8. 在Matlab计算照度平均值 ho^c#>81  
    9. 返回数据到FRED中 ?S=y>b9R
