    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。 hu >wcOt  
    <\$?.tTZ {  
    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: P @Fx6  
    enableservice('AutomationServer', true) ^%m{yf#  
    enableservice('AutomationServer') "<Yxt"Z4  
    &?TXsxf1Zh  
    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 1h#/8 X  
    $KhD>4^ jL  
    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: 6ma.FvSIM  
    1. 在FRED脚本编辑界面找到参考. ("YWJJ'H  
    2. 找到Matlab Automation Server Type Library Dbb=d8utE  
    3. 将名字改为MLAPP A%X=yqY  
    xLms|jS  
    / U!xh3  
    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。 4 9HP2E

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =A~5?J=  
    1. 创建Matlab服务器。 ;mg.} fI  
    2. 移动探测面对于前一聚焦面的位置。 4`Zo Ar-5|  
    3. 在探测面追迹光线 s8 u`v1  
    4. 在探测面计算照度 76] Z~^Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,tDLpnB@;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s8'!1rHd  
    7. 用Matlab画出照度数据 ko|M2\  
    8. 在Matlab计算照度平均值 IwOL1\'T4  
    9. 返回数据到FRED中 k!G{#(++&6
