    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。 X<9jBj/t  
    DB-4S-2  
    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{J<7I e"*  
    enableservice('AutomationServer', true) r5xu#%hgp;  
    enableservice('AutomationServer') #G:~6^A  
    4nzUDeI3MG  
    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 MR=>DcR  
    oIdMDp^$  
    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: k%?wNk>  
    1. 在FRED脚本编辑界面找到参考. pP;GDW4  
    2. 找到Matlab Automation Server Type Library \/*r45!  
    3. 将名字改为MLAPP ( ?3 )l   
    'KMyaEh.u  
    ~v$gk   
    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。 u*  G|TF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: xV @X%E  
    1. 创建Matlab服务器。 $/ew'h9q  
    2. 移动探测面对于前一聚焦面的位置。 JeU|e$I4>  
    3. 在探测面追迹光线 6H\3  
    4. 在探测面计算照度 J~9l+?  
    5. 使用PutWorkspaceData发送照度数据到Matlab ABvB1[s#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 I:Wrwd  
    7. 用Matlab画出照度数据 J'`,];su  
    8. 在Matlab计算照度平均值 !>W _3Ea  
    9. 返回数据到FRED中 @x3x/g U
