    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。 a+uSCs[C  
    t}c ymX~  
    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: "n}J6   
    enableservice('AutomationServer', true) QO[!  
    enableservice('AutomationServer') eL0U5>#  
    J)x-Yhe  
    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 SBzJQt@Hs

    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: #:3ca] k  
    1. 在FRED脚本编辑界面找到参考. O B_g:T  
    2. 找到Matlab Automation Server Type Library g`d5OHvO o  
    3. 将名字改为MLAPP <wW#Wnc]  
    8uP,#D<wZ  
    #OqQD6  
    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。 E<:XHjm

    现在将脚本代码公布如下,此脚本执行如下几个步骤: d/v{I  
    1. 创建Matlab服务器。 o:.={)rX  
    2. 移动探测面对于前一聚焦面的位置。 ]e$mTRi*  
    3. 在探测面追迹光线 @mSdksB/L  
    4. 在探测面计算照度 ?w#V<3=  
    5. 使用PutWorkspaceData发送照度数据到Matlab ['~3"lK^O  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s{(aW5$!s  
    7. 用Matlab画出照度数据 f7Y0L8D  
    8. 在Matlab计算照度平均值 @i'RIL}  
    9. 返回数据到FRED中 9.{u2a\
