    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。 N#Rb8&G)b  
    Q k}RcP  
    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: VIdKe&,  
    enableservice('AutomationServer', true) |P]W#~Y-  
    enableservice('AutomationServer') C<C$df  
    5e. aTW;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 ]}lt^7\=

    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: 1s(T#jh  
    1. 在FRED脚本编辑界面找到参考. YA,~qT|  
    2. 找到Matlab Automation Server Type Library LUD .  
    3. 将名字改为MLAPP SI~jM:S}

    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。 'y; Kj

    1. 创建Matlab服务器。 I3.. Yk%7  
    2. 移动探测面对于前一聚焦面的位置。 aGC3&c[Wx  
    3. 在探测面追迹光线 60^j<O  
    4. 在探测面计算照度 %<-OdyM  
    5. 使用PutWorkspaceData发送照度数据到Matlab R`@T<ob)  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =_pSfKR;  
    7. 用Matlab画出照度数据 5?;<^J  
    8. 在Matlab计算照度平均值 GGEM&0*  
    9. 返回数据到FRED中 GIzB1cl:
