    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。 sPvjJr"s  
     bU$M)  
    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: tv%B=E!r  
    enableservice('AutomationServer', true) </D )i  
    enableservice('AutomationServer') T l8`3`e  
    pyp0SGCM:  
    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 yaYJmhG  
    y#i` i  
    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: _ O;R  
    1. 在FRED脚本编辑界面找到参考. #Ve@D@d[  
    2. 找到Matlab Automation Server Type Library .+&M,% x  
    3. 将名字改为MLAPP 3,1HD_  
    `o?PLE;)p  
    |z?c>.  
    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。 (e4 #9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: j+("4b'  
    1. 创建Matlab服务器。 '<xV]k|v  
    2. 移动探测面对于前一聚焦面的位置。 eu'S~c-l  
    3. 在探测面追迹光线 .JV y}^Q\  
    4. 在探测面计算照度 cVl i^*se  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q096M 0m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h !?rk|  
    7. 用Matlab画出照度数据 Q^):tO]!Ma  
    8. 在Matlab计算照度平均值 h)Ol1[y`  
    9. 返回数据到FRED中 K9ek
