    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。 W+5<=jXFB  
    x(r~<a[  
    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: IMT]!j&Y,  
    enableservice('AutomationServer', true) Rv=rO|&]  
    enableservice('AutomationServer') q y\Z2k  
    @SX-=Nr  
    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 Xc H_Y  
    [!'fE #"a  
    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: ,)beK*Iw  
    1. 在FRED脚本编辑界面找到参考. }\Ri:&?  
    2. 找到Matlab Automation Server Type Library 6-6ha7]s  
    3. 将名字改为MLAPP #*|Gp_l+%  
    w;=g$Bn  
    T-)lnrs^  
    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。 !=SBeq

    现在将脚本代码公布如下,此脚本执行如下几个步骤: CA[3 R  
    1. 创建Matlab服务器。 *MD\YFXR  
    2. 移动探测面对于前一聚焦面的位置。 ,B8u?{O  
    3. 在探测面追迹光线 s"-gnW  
    4. 在探测面计算照度 -RKqbfmi=  
    5. 使用PutWorkspaceData发送照度数据到Matlab }T1.~E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 29tih{ xx  
    7. 用Matlab画出照度数据 6t!PHA  
    8. 在Matlab计算照度平均值 `SM37({c  
    9. 返回数据到FRED中 k,GAHM"'
