    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。 jKo9y  
    GU9G5S.  
    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: wnK6jMjkSf  
    enableservice('AutomationServer', true) FCOa|IKsN  
    enableservice('AutomationServer') HG< z,gE 2  
    ?B$L'i[l  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 P-$ ,

    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: xK)<7 63q>  
    1. 在FRED脚本编辑界面找到参考. A.@wGy4  
    2. 找到Matlab Automation Server Type Library xIW]e1pu=(  
    3. 将名字改为MLAPP Nd_A8H,&B

    'r ^ .Ao5  
    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。 \jV2":[% c

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >mpNn  
    1. 创建Matlab服务器。 Mk=*2=d  
    2. 移动探测面对于前一聚焦面的位置。 r}sO},i  
    3. 在探测面追迹光线 63_#*6Pv28  
    4. 在探测面计算照度 %Y0BPTt$  
    5. 使用PutWorkspaceData发送照度数据到Matlab =cb!2%?}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 dtTfV.y4w  
    7. 用Matlab画出照度数据  LAM{ ,?~  
    8. 在Matlab计算照度平均值 o8H\l\(  
    9. 返回数据到FRED中 N 3O!8A_
