[推荐]FRED案例-FRED如何调用Matlab [复制链接]

qA25P<  
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。 _?bF;R  
l~@ -oE  
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： \!0~$?_)P  
enableservice('AutomationServer', true) n2["Ln mO  
    enableservice('AutomationServer') &##JZ  
/CbM-jf  
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。 h<WTN_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： =}e{U&CX  
1. 在FRED脚本编辑界面找到参考. 6}\J-A/  
2. 找到Matlab Automation Server Type Library lZ`@ }^&  
    3. 将名字改为MLAPP hs

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。 <#T#+uO

现在将脚本代码公布如下，此脚本执行如下几个步骤： g\aq#QV  
1. 创建Matlab服务器。 &>ykkrY  
2. 移动探测面对于前一聚焦面的位置。 1nE`Wmo.2  
3. 在探测面追迹光线 CzmB76zy.  
4. 在探测面计算照度 TF,([p*  
5. 使用PutWorkspaceData发送照度数据到Matlab Bv6~!p  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d#I; e  
7. 用Matlab画出照度数据 P4s,N|bs`  
8. 在Matlab计算照度平均值 >[P`$XkXd4  
9. 返回数据到FRED中 edlsS}8^
