    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。 s7} )4.vO  
    6Ymk8.PF  
    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: 5&@U T  
    enableservice('AutomationServer', true) S c Kfr  
    enableservice('AutomationServer') /n:fxdhe  
    hI{Yg$H1  
    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 ,sl.:C4  
    )d`$2D&iY  
    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: dtl<  
    1. 在FRED脚本编辑界面找到参考. ttVSgKAsm  
    2. 找到Matlab Automation Server Type Library rP4@K%F9jB  
    3. 将名字改为MLAPP b7j#a#  
    =oDrN7`,B  
    wJkkc9Rh'(  
    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。 GqxK|G1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: iNSJOS  
    1. 创建Matlab服务器。 Mv =;+?z!  
    2. 移动探测面对于前一聚焦面的位置。  \RO Sd  
    3. 在探测面追迹光线 c'R|Wyf  
    4. 在探测面计算照度 xII!2.  
    5. 使用PutWorkspaceData发送照度数据到Matlab tH(#nx8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '~J6 mojE  
    7. 用Matlab画出照度数据 [?*^&[  
    8. 在Matlab计算照度平均值 \_bX2Lg  
    9. 返回数据到FRED中 >.4Sx~VH2
