    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。 r@ *A   
    3S|;yOl#X  
    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:  v2=!*  
    enableservice('AutomationServer', true) J9t?]9.,:  
    enableservice('AutomationServer') r!gCh`PiK  
    ^dKaa  
    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 UNLNY,P/!)  
    $P9$ ,w4  
    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: QgM_SY|Rj  
    1. 在FRED脚本编辑界面找到参考. Wk#-LkI  
    2. 找到Matlab Automation Server Type Library V~"d`j  
    3. 将名字改为MLAPP U$J_:~

    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。 I{ZPv"9j^

    1. 创建Matlab服务器。 CKw)J}z  
    2. 移动探测面对于前一聚焦面的位置。 L k+1r8  
    3. 在探测面追迹光线 5kZ yiC*  
    4. 在探测面计算照度 *K)53QKlE  
    5. 使用PutWorkspaceData发送照度数据到Matlab #IA(*oM  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !0+Ex F  
    7. 用Matlab画出照度数据 =zGz|YI*?  
    8. 在Matlab计算照度平均值 uKzz/Y{  
    9. 返回数据到FRED中 T0)y5
