    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。  De2$:?  
    hP}-yW6]  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ~r_2V$sC2  
    enableservice('AutomationServer', true) kD(#LM<9s  
    enableservice('AutomationServer') .}Eckqkp  
    + w'q5/`  
    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 "}vxHN#  
    *7w!~mn[m  
    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: 9_O6Sl  
    1. 在FRED脚本编辑界面找到参考. KL./  
    2. 找到Matlab Automation Server Type Library .FN 6/N\  
    3. 将名字改为MLAPP <}T7;knO

    .03Rp5+v  
    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。 EQ.K+d*K][

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^7a@?|,q8  
    1. 创建Matlab服务器。 djqw5kO:R  
    2. 移动探测面对于前一聚焦面的位置。 G[6i\Et   
    3. 在探测面追迹光线 ZQ>Q=eCs 1  
    4. 在探测面计算照度 B#?rW*yEe  
    5. 使用PutWorkspaceData发送照度数据到Matlab ZL:SJ,C  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 wbvOf X  
    7. 用Matlab画出照度数据 [] el4.J,  
    8. 在Matlab计算照度平均值 xz, o Mlw  
    9. 返回数据到FRED中 `X)A$lLr
