    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。 J-f0  
    V$_0VN'+Z  
    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: s*X\%!l9  
    enableservice('AutomationServer', true) [ O)Zof  
    enableservice('AutomationServer') 2Ee1mbZVw8  
    k:qou})#4  
    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 ).S<{zm7  
    w +Z};C  
    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: UKBMGzu2:  
    1. 在FRED脚本编辑界面找到参考. WuQYEbap  
    2. 找到Matlab Automation Server Type Library lG+ltCc$9  
    3. 将名字改为MLAPP 5q#|sVT7R  
    3d<HIG^W}  
    ;E"mB4/)  
    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。 iHn]yv3 #

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Cr%r<*s  
    1. 创建Matlab服务器。 U:|v(U$"?  
    2. 移动探测面对于前一聚焦面的位置。 F)5Aq H/p  
    3. 在探测面追迹光线 *Kkw,qp/  
    4. 在探测面计算照度 O*v+<|0!l  
    5. 使用PutWorkspaceData发送照度数据到Matlab pdHb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bx^EaXj(r  
    7. 用Matlab画出照度数据 T!A}ipqb  
    8. 在Matlab计算照度平均值 B3t>M) 9  
    9. 返回数据到FRED中 ?t42=nvf
