    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。 iw$n*1M  
    {'QA0K  
    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: laQM*FLg  
    enableservice('AutomationServer', true) *{y/wgX  
    enableservice('AutomationServer') 5ecAev^1-  
    -zq_W+)ks  
    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 i8tH0w/(M  
    cS'|c06  
    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: F^v <z)x  
    1. 在FRED脚本编辑界面找到参考. 7|"gMw/  
    2. 找到Matlab Automation Server Type Library >c~ Fg s  
    3. 将名字改为MLAPP HZ#<+~J

    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。 qOV6Kh)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !H5r+%Oo|  
    1. 创建Matlab服务器。 *W#_W]Tu  
    2. 移动探测面对于前一聚焦面的位置。 YXR%{GUP[  
    3. 在探测面追迹光线 ,pgpu !  
    4. 在探测面计算照度 jtMN)TM  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8mCL3F  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (mOUbO8  
    7. 用Matlab画出照度数据 {hr+ENgV  
    8. 在Matlab计算照度平均值 d`z),A=  
    9. 返回数据到FRED中 ZkyH<Aa
