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。 Z,sv9{4r  
F~T]u2qt  
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: %-)H^i~]%  
enableservice('AutomationServer', true) QKyo`g7  
enableservice('AutomationServer') ;nep5!s;<  
o|>'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。 +AR5W(&  
-=%@L&y1  
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: PPb7%2r  
1. 在FRED脚本编辑界面找到参考. {K+i cTL3  
2. 找到Matlab Automation Server Type Library }Ga\wV  
3. 将名字改为MLAPP 6N!Q:x^4(T  
g<l1zo`_  
 'C`U"I  
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。 H\h3 TdL

现在将脚本代码公布如下,此脚本执行如下几个步骤: =y [M\m  
1. 创建Matlab服务器。 igkYX!0#8O  
2. 移动探测面对于前一聚焦面的位置。 M$y+q ^  
3. 在探测面追迹光线 s8ywKTR-  
4. 在探测面计算照度 W}m)cn3@  
5. 使用PutWorkspaceData发送照度数据到Matlab q1z"-~i )E  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ZIf  
7. 用Matlab画出照度数据 KV]X@7`@  
8. 在Matlab计算照度平均值 ,=UK}*e"  
9. 返回数据到FRED中 gbI^2=YT'
