    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。 +PCsp'D d  
    u-31$z<<5}  
    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: X2 Z E9b  
    enableservice('AutomationServer', true) vP_V%5~yN  
    enableservice('AutomationServer') J?Ed^B-  
    tt|v opz  
    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 `]+-z +  
    B/iRR2h  
    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: 1X5*V!u  
    1. 在FRED脚本编辑界面找到参考. x/7d!>#;  
    2. 找到Matlab Automation Server Type Library 500qg({2]  
    3. 将名字改为MLAPP R5y+bMZ

    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。 `I\)Kk@*b9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Cb{n4xKW6  
    1. 创建Matlab服务器。 P3due|4M  
    2. 移动探测面对于前一聚焦面的位置。 ?=UIx24W  
    3. 在探测面追迹光线 rvdhfM!-A  
    4. 在探测面计算照度 S.!0~KR: U  
    5. 使用PutWorkspaceData发送照度数据到Matlab .^?^QH3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 cH5@Jam  
    7. 用Matlab画出照度数据 $'9b,- e  
    8. 在Matlab计算照度平均值 nA!Xb'y&  
    9. 返回数据到FRED中 c|kQ3(
