    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。 1ciP+->$  
    ~U ?cL-`n  
    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: hY/SR'8  
    enableservice('AutomationServer', true) 2vu"PeU9  
    enableservice('AutomationServer') JU/K\S2%,  
    ;:8_H0X'K  
    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 ^\ {%(i9  
    K (Z d-U  
    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: ZMy7z|  
    1. 在FRED脚本编辑界面找到参考. Wi hQj  
    2. 找到Matlab Automation Server Type Library 2EycFjO  
    3. 将名字改为MLAPP Qh%7RGh_  
    a}0\kDe  
    a?M<r>  
    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。 =n i&*&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: vC&y:XMt,`  
    1. 创建Matlab服务器。 hTf]t  
    2. 移动探测面对于前一聚焦面的位置。 #B;`T[  
    3. 在探测面追迹光线 OZQhT)nS]  
    4. 在探测面计算照度 dB^J}_wp  
    5. 使用PutWorkspaceData发送照度数据到Matlab N[){yaj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bX=ht^e [  
    7. 用Matlab画出照度数据 +, p  
    8. 在Matlab计算照度平均值 X./8 PK?&  
    9. 返回数据到FRED中 c^Rz?2x
