    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。 d9jD?HgM(  
    Tw*p^rU  
    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: !.pcldx  
    enableservice('AutomationServer', true)  H4YA  
    enableservice('AutomationServer') br k*;  
    ,(sE|B#s  
    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 \4<|QE

    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: 6;!)^b  
    1. 在FRED脚本编辑界面找到参考. s?9Y3]&+&M  
    2. 找到Matlab Automation Server Type Library c\ ZnGI\|  
    3. 将名字改为MLAPP ;+o6"ky5

    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。 )~nieQEZQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "j8=%J{  
    1. 创建Matlab服务器。 (w(k*b/  
    2. 移动探测面对于前一聚焦面的位置。 8~RJnwF^  
    3. 在探测面追迹光线 T9kc(i'  
    4. 在探测面计算照度 ln , 9v  
    5. 使用PutWorkspaceData发送照度数据到Matlab ${wp}<u_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 suLC7x`Z  
    7. 用Matlab画出照度数据 i tk/1  
    8. 在Matlab计算照度平均值 L=HnVgBs  
    9. 返回数据到FRED中 ;qWSfCt/^
