    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。 8x!+tw7  
    D$Kz9GVZq  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: u'#`yTB6b  
    enableservice('AutomationServer', true) h85 (N  
    enableservice('AutomationServer') d3\OHkM0^  
    )PsN_ 42~  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 s$js5 ou  
    U)SM),bE[  
    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: oqm  
    1. 在FRED脚本编辑界面找到参考. T_(qN;_  
    2. 找到Matlab Automation Server Type Library }C_G0'"F  
    3. 将名字改为MLAPP Q x9>,e6+  
    ._8xY$l$  
    BUcaj.S  
    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。 R>/QA RX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: '*o7_Ez-{  
    1. 创建Matlab服务器。 [] GthF  
    2. 移动探测面对于前一聚焦面的位置。 z Y$X|= f  
    3. 在探测面追迹光线 8o*\W$K@  
    4. 在探测面计算照度 L?Kz P.(t+  
    5. 使用PutWorkspaceData发送照度数据到Matlab %RCl+hOP.h  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [[";1l  
    7. 用Matlab画出照度数据 "R@$Wu53|  
    8. 在Matlab计算照度平均值 {bAWc.  
    9. 返回数据到FRED中 O;"*_Xq(`
