    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。 OqtGKda  
    !GOaBs  
    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: C% -Tw]T$_  
    enableservice('AutomationServer', true) @3`5(xwzm  
    enableservice('AutomationServer') zlMh^+rMX  
    sn"((BsO<  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 .*zN@y3  
    rr# nBhh8  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ~${~To8$CW  
    1. 在FRED脚本编辑界面找到参考. 161P%sGx2  
    2. 找到Matlab Automation Server Type Library i/:L^SQAq  
    3. 将名字改为MLAPP 4`O[U#?

    WD5J2EePT  
    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。 zx@!8Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Y?^liI`#  
    1. 创建Matlab服务器。 zgD?e?yPO  
    2. 移动探测面对于前一聚焦面的位置。 0/HFLz'  
    3. 在探测面追迹光线 $dM_uSt  
    4. 在探测面计算照度 FJ_JaIby  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0C zQel)L:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =O}I{dNKZV  
    7. 用Matlab画出照度数据 @CNJpQ ujn  
    8. 在Matlab计算照度平均值 Snr(<u  
    9. 返回数据到FRED中 f' A$':Y
