    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。 ;v m$F251  
    J_d!` Hhe  
    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: Y))x'<T'Q  
    enableservice('AutomationServer', true) /JQY_>@W  
    enableservice('AutomationServer') )KKmV6>b  
    /{!?e<N>  
    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 {Z1^/F v3  
    }TG=ZVi  
    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: 'a=' (,%  
    1. 在FRED脚本编辑界面找到参考. vJsx_ i\i  
    2. 找到Matlab Automation Server Type Library @QAI 0ZY  
    3. 将名字改为MLAPP "p"~fN /I9  
    oT*qMLdn  
    THmmf_w@  
    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。 NU%<Ws=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Bn5$TiTcl  
    1. 创建Matlab服务器。 Pvz\zRq  
    2. 移动探测面对于前一聚焦面的位置。 /EV _Y|(-  
    3. 在探测面追迹光线 2!";?E  
    4. 在探测面计算照度 -$o4WSd~  
    5. 使用PutWorkspaceData发送照度数据到Matlab b|nh4g  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z<,-:=BC"  
    7. 用Matlab画出照度数据 n0opb [?  
    8. 在Matlab计算照度平均值 i7foZ\btFc  
    9. 返回数据到FRED中 M5c~-}Ay
