    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。 W7W3DBKtSm  
    RCCv>o  
    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: $ {@q?iol  
    enableservice('AutomationServer', true) .5^a;`-+  
    enableservice('AutomationServer') iW;}%$lVX  
    m1i4,  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 !4pr{S  
    ennR@pg  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: \{:%v#ZZ  
    1. 在FRED脚本编辑界面找到参考. UIz:=DJ  
    2. 找到Matlab Automation Server Type Library U~CdU  
    3. 将名字改为MLAPP +q l  
    @$EjD3Z-  
    /'mrDb_ip  
    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。 ;raz6DRO

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @+$cZ3,  
    1. 创建Matlab服务器。 B%2L1T=  
    2. 移动探测面对于前一聚焦面的位置。 RA} U#D:$i  
    3. 在探测面追迹光线 ia_Z\q  
    4. 在探测面计算照度 Y+5"uq<'  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ma>:_0I5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 T!1SMo^  
    7. 用Matlab画出照度数据 8.[&wy U  
    8. 在Matlab计算照度平均值 ' *}^@[&  
    9. 返回数据到FRED中 2+,5p
