    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。  tEP^w  
    1{";u"q  
    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: )#*c|.  
    enableservice('AutomationServer', true) #docBsHX&s  
        enableservice('AutomationServer') ( 7Y :3  
    rD$7;  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 YWq[)F@0G  
    r=@h}TKv{I  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: >|z=-hqPK  
    1. 在FRED脚本编辑界面找到参考. :Q\h'$C  
    2. 找到Matlab Automation Server Type Library o/=K:5  
        3. 将名字改为MLAPP _Q.3X[88C

    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。 [d dEt

    现在将脚本代码公布如下,此脚本执行如下几个步骤: xZ9y*Gv\=  
    1. 创建Matlab服务器。 xn}'!S2-b  
    2. 移动探测面对于前一聚焦面的位置。 7Jc=`Zm'  
    3. 在探测面追迹光线 /I6?t= ?<  
    4. 在探测面计算照度 06Uxd\E~  
    5. 使用PutWorkspaceData发送照度数据到Matlab 3)dT+lZ  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 !4oYQB  
    7. 用Matlab画出照度数据 Eda sGCo  
    8. 在Matlab计算照度平均值 \19XDqf8  
    9. 返回数据到FRED中 )(DV~1r=
