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。 SRN9(LN  
""3m!qn#  
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: wp.e3l  
enableservice('AutomationServer', true) :ZS 8Zm"  
enableservice('AutomationServer') 7&V^BW  
/ 7XdV  
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。 1L8ULxi_?]

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: no NF;zT  
1. 在FRED脚本编辑界面找到参考. 4c[)}8\  
2. 找到Matlab Automation Server Type Library MW$H/:3  
3. 将名字改为MLAPP 8='21@wrN  
t"/"Ge#a  
b+].Uc  
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。 eM=)>zl

现在将脚本代码公布如下,此脚本执行如下几个步骤: k> &s( b  
1. 创建Matlab服务器。 DJYXC,r  
2. 移动探测面对于前一聚焦面的位置。 N~; khS]  
3. 在探测面追迹光线 .(7C)P{ .0  
4. 在探测面计算照度 6~h1iY_~  
5. 使用PutWorkspaceData发送照度数据到Matlab w<~<(5mM5;  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Eqmv`Z [_  
7. 用Matlab画出照度数据 gSr}p$N  
8. 在Matlab计算照度平均值 nj^q@h  
9. 返回数据到FRED中 _SIs19"lR
