    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。 Lwgk}!KR  
    A{Giz&p  
    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: qw[)$icP  
    enableservice('AutomationServer', true) d$<HMs:o@  
    enableservice('AutomationServer') y\Z7]LHCqw  
    4oLrCQZ\  
    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 &1:xY.Zs_

    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: k<uC[)_  
    1. 在FRED脚本编辑界面找到参考. ysA~Nq@  
    2. 找到Matlab Automation Server Type Library xW*L^97 ;  
    3. 将名字改为MLAPP '+BcPB?E  
    50Z$3T  
    XW6Ewrm=vT  
    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。 ^B2>lx\n

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fU_itb(  
    1. 创建Matlab服务器。 ^w4FqdGM  
    2. 移动探测面对于前一聚焦面的位置。 Klh7&HzR  
    3. 在探测面追迹光线 xtL_,ug  
    4. 在探测面计算照度 ?4wS/_C/  
    5. 使用PutWorkspaceData发送照度数据到Matlab epi{Ayb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vBCQ-l<Ub  
    7. 用Matlab画出照度数据 JB(~O`  
    8. 在Matlab计算照度平均值 WE \912j  
    9. 返回数据到FRED中 bLoAtI
