    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。 5?M d  
    ;eQOBGX9  
    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: H\!p%Y  
    enableservice('AutomationServer', true) I/V lH:o  
    enableservice('AutomationServer') 4te QG  
     5i|DJ6  
    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 ~+OAAkJ9

    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: eemw I  
    1. 在FRED脚本编辑界面找到参考. -Mx\W|YK  
    2. 找到Matlab Automation Server Type Library bxR6@  
    3. 将名字改为MLAPP JT(6Uf  
    S%{^@L+V  
    uS}qy-8J  
    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。 op5G}QZ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: .XTR HL*:  
    1. 创建Matlab服务器。 jPc"qER!  
    2. 移动探测面对于前一聚焦面的位置。 !]*Cwbh. u  
    3. 在探测面追迹光线 '2X6 >6`w  
    4. 在探测面计算照度 e/s8?l  
    5. 使用PutWorkspaceData发送照度数据到Matlab O~~WP*N  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 MIF`|3$,  
    7. 用Matlab画出照度数据 Z\. n6  
    8. 在Matlab计算照度平均值 %!X9>i>
