FRED如何调用Matlab

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。 U_5`  
lxL.ztL  
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: F5 ]<=i  
enableservice('AutomationServer', true) )&j`5sSXcr  
enableservice('AutomationServer') jjj<B'zt  
Q*>)W{H&)  
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。 ?<!q F:r:

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: @}d;-m~  
1. 在FRED脚本编辑界面找到参考. Ia#!T"]@W6  
2. 找到Matlab Automation Server Type Library Cj8&wz}ez  
3. 将名字改为MLAPP W34xrm  
H u;"TG  
WDIin6u-  
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。 k9rws

现在将脚本代码公布如下,此脚本执行如下几个步骤: ?/3wO/7[  
1. 创建Matlab服务器。 V )<>W_g  
2. 移动探测面对于前一聚焦面的位置。 "frZ%mv  
3. 在探测面追迹光线 FFcCoPX_  
4. 在探测面计算照度 I </P_:4G  
5. 使用PutWorkspaceData发送照度数据到Matlab ?CQE6ch  
6. 使用PutFullMatrix发送标量场数据到Matlab中 c]|vg=W  
7. 用Matlab画出照度数据  lrv-[}}  
8. 在Matlab计算照度平均值 +QFKaS<sn  
9. 返回数据到FRED中 4@-tT;$
