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。 4"$K66yk@  
ahagt9[,:F  
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: \Mk;Y  
enableservice('AutomationServer', true) xkv2#"*v  
enableservice('AutomationServer') L2s)B  
V K/;ohTTP  
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。 7%p[n;-o&

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: l26DPtWi  
1. 在FRED脚本编辑界面找到参考. [al,UO  
2. 找到Matlab Automation Server Type Library FA 1E`AdU  
3. 将名字改为MLAPP !^Mk5E(  
zk+&5d 4(  
qXPT1%+)y  
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。 =}S*]Me5

现在将脚本代码公布如下,此脚本执行如下几个步骤: jr@u  
1. 创建Matlab服务器。 .r9-^01mG  
2. 移动探测面对于前一聚焦面的位置。 )^+v*=Dc-i  
3. 在探测面追迹光线 pg3B^  
4. 在探测面计算照度 Nrl&"IK|J  
5. 使用PutWorkspaceData发送照度数据到Matlab 8l|v#^v  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ;IhkGPpWP  
7. 用Matlab画出照度数据 bP;cDQ(g  
8. 在Matlab计算照度平均值 wH&Rjn  
9. 返回数据到FRED中 M[5zn
