    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。 E>v~B;@  
    :#;?dMkTY  
    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: "zc!QHpSd  
    enableservice('AutomationServer', true) "w1jr 6"  
    enableservice('AutomationServer') o,I642R~  
    g?wogCs5  
    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 @"0qS:s]X

    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: 8%B @[YDe  
    1. 在FRED脚本编辑界面找到参考. -)GfSk   
    2. 找到Matlab Automation Server Type Library Zup?nP2GkT  
    3. 将名字改为MLAPP !j@ 8:j0WY

    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。 g(Nf.hko

    现在将脚本代码公布如下,此脚本执行如下几个步骤: W` V  
    1. 创建Matlab服务器。 2o;M:+KQ)  
    2. 移动探测面对于前一聚焦面的位置。 Qn7e6u@V  
    3. 在探测面追迹光线 `,O^=HBM  
    4. 在探测面计算照度 M 5h U.3.L  
    5. 使用PutWorkspaceData发送照度数据到Matlab K||85l?<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 WUWQcJj  
    7. 用Matlab画出照度数据 ?{'Q}%  
    8. 在Matlab计算照度平均值 1C{~!=6#  
    9. 返回数据到FRED中 (;h\)B!o
