    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。 #C3.Jef  
    O1mKe%'|  
    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: &`XVq" 7  
    enableservice('AutomationServer', true) >e"#'K0?\  
    enableservice('AutomationServer') _ORvo{[:  
    VU d\QR-  
    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 !GGkdg*-*9

    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: b>N8F^}~O  
    1. 在FRED脚本编辑界面找到参考. K6)j0 ]K1  
    2. 找到Matlab Automation Server Type Library Ez=Olbk  
    3. 将名字改为MLAPP UZsH9 o

    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。 xK\d4 "

    1. 创建Matlab服务器。 /gkX38  
    2. 移动探测面对于前一聚焦面的位置。 3kMf!VL  
    3. 在探测面追迹光线 3jC_AO%T  
    4. 在探测面计算照度 /RC7"QzL  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,Vk3kmuvr]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #?9;uy<j.q  
    7. 用Matlab画出照度数据 J~UuS+Ufv  
    8. 在Matlab计算照度平均值 <yFu*(Q  
    9. 返回数据到FRED中 `lt"[K<
