    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。 0?)U?=>]p  
    kB|j N~  
    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: ^4Nk13  
    enableservice('AutomationServer', true) JArSJ:}  
    enableservice('AutomationServer') v/n4Lp$W^  
    [dG&"%5vD  
    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 9H@I<`qGC

    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 SJGp`  
    1. 在FRED脚本编辑界面找到参考. OH`| c  
    2. 找到Matlab Automation Server Type Library W|IMnK-  
    3. 将名字改为MLAPP 1Sk=;Bic

    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。 ].W)eMC*c(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: + .Pv:7gh  
    1. 创建Matlab服务器。 +mM=`[Z`??  
    2. 移动探测面对于前一聚焦面的位置。 ^Eu]i  
    3. 在探测面追迹光线 #fq%903=  
    4. 在探测面计算照度 >s 4"2X  
    5. 使用PutWorkspaceData发送照度数据到Matlab l^.d 3b  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -__RFxG  
    7. 用Matlab画出照度数据 :}QBrd  
    8. 在Matlab计算照度平均值 Tr}z&efY  
    9. 返回数据到FRED中 =o N(1k^
