    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。 Nkt(1?:-'  
    9&=~_,wJd  
    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: qJj;3{X2  
    enableservice('AutomationServer', true) iNR6BP W  
    enableservice('AutomationServer') i6zfr|`@  
    DYU+?[J  
    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 ;%Jw9G\h  
    4}{HRs?  
    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: .N99=%[}h  
    1. 在FRED脚本编辑界面找到参考. w<*tbq  
    2. 找到Matlab Automation Server Type Library wj/\ !V!  
    3. 将名字改为MLAPP 8 YAUy\

    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。 q"5iza__H

    现在将脚本代码公布如下,此脚本执行如下几个步骤: AHP_B&s,Qe  
    1. 创建Matlab服务器。 e%&2tf4  
    2. 移动探测面对于前一聚焦面的位置。 EZz Ox(g  
    3. 在探测面追迹光线 %0}qMYS  
    4. 在探测面计算照度 <8[BB7  
    5. 使用PutWorkspaceData发送照度数据到Matlab Z&%#,0>]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 pvJ@$L `'  
    7. 用Matlab画出照度数据 D*Y4B ?,  
    8. 在Matlab计算照度平均值 @kUCc1LT  
    9. 返回数据到FRED中 a3 <D1"
