    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。 p1CY?K  
    8LB+}N(8f  
    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: ) =sm{R%T  
    enableservice('AutomationServer', true) (@mvNlc:  
    enableservice('AutomationServer') cs,%Zk.xjw  
    G=(F-U;*  
    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 GYZzWN}U  
    ,qyH B2v  
    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: q*,];j/>k  
    1. 在FRED脚本编辑界面找到参考. yX?& K}JI  
    2. 找到Matlab Automation Server Type Library J6Cw1Pi  
    3. 将名字改为MLAPP $#1i@dI  
    h0L *8P`t  
    [P407Sa"  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 7$k[cL1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O:WFh;c  
    1. 创建Matlab服务器。 t=Tu-2,k  
    2. 移动探测面对于前一聚焦面的位置。 j!xt&t4D  
    3. 在探测面追迹光线 z`]'~  
    4. 在探测面计算照度 1 @tVfn}  
    5. 使用PutWorkspaceData发送照度数据到Matlab \|RP-8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G ,An8GR%&  
    7. 用Matlab画出照度数据 !0{":4 \  
    8. 在Matlab计算照度平均值 w-pdpbHV  
    9. 返回数据到FRED中 }hv>LL
