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。 #S5vX<"9  
5P4 >xv[  
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: LO229`ARr|  
enableservice('AutomationServer', true) STMcMm3  
enableservice('AutomationServer') D~Su82 2  
tg:x}n  
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。 @`yfft  
u/AN| y  
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: lF<(yF5  
1. 在FRED脚本编辑界面找到参考. %rsW:nl  
2. 找到Matlab Automation Server Type Library K67x.PZ  
3. 将名字改为MLAPP k&2I(2S  
nC w1H kW  
%`~8j H@  
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。 V2*b f`/V

现在将脚本代码公布如下,此脚本执行如下几个步骤: 1/z1~:Il  
1. 创建Matlab服务器。 $]9d((u4  
2. 移动探测面对于前一聚焦面的位置。 &lD4-_2J  
3. 在探测面追迹光线 O/-xkzR*  
4. 在探测面计算照度 n\QG-?%Pi  
5. 使用PutWorkspaceData发送照度数据到Matlab C$_H)I  
6. 使用PutFullMatrix发送标量场数据到Matlab中 .R1)i-^  
7. 用Matlab画出照度数据 3k=q>~& @  
8. 在Matlab计算照度平均值 e&:fzO<~I  
9. 返回数据到FRED中 qdOS=7]W
