    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。 hkSpG{;7  
    ~(Gv/x  
    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: B' 6^E#9  
    enableservice('AutomationServer', true) b1{~j]"$L  
    enableservice('AutomationServer') J'^s5hxn+0  
    dj4 g  
    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 _i~n!v  
    ,pir,Eozg  
    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: HRi~TZ?\  
    1. 在FRED脚本编辑界面找到参考. xG0IA 7  
    2. 找到Matlab Automation Server Type Library {n%-^9b1{&  
    3. 将名字改为MLAPP FW&P`Iu  
    9x.vz  
    Pa 2HFy2  
    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。 t+Mr1e

    现在将脚本代码公布如下,此脚本执行如下几个步骤: USu/Y29  
    1. 创建Matlab服务器。 kbBD+*  
    2. 移动探测面对于前一聚焦面的位置。 k6rX/ocu  
    3. 在探测面追迹光线 nS[0g^}  
    4. 在探测面计算照度 *2crhI*@>  
    5. 使用PutWorkspaceData发送照度数据到Matlab q]:+0~cz  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 wE3^6  
    7. 用Matlab画出照度数据 vq_W zxaG  
    8. 在Matlab计算照度平均值 N%6jZmKip  
    9. 返回数据到FRED中 !Jb?r SJ.h
