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。 ;r}>1LhN  
6bW:&IPQ;  
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: 4;hgi[  
enableservice('AutomationServer', true) J}vxK H#=  
enableservice('AutomationServer') /P-Eg86V'  
}|7y.*  
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。 (~<9\ZJs  
td6$w:SN,l  
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: T)NnWEB  
1. 在FRED脚本编辑界面找到参考. C*I~14  
2. 找到Matlab Automation Server Type Library #=hI}%n  
3. 将名字改为MLAPP G$"$k=[  
Ydr/ T/1  
Cp@' k;(  
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。 AqzPwO^

现在将脚本代码公布如下,此脚本执行如下几个步骤: h^D]@H  
1. 创建Matlab服务器。 Z$? Ql@M  
2. 移动探测面对于前一聚焦面的位置。 0` {6~p  
3. 在探测面追迹光线 ?5<Q+ G0r  
4. 在探测面计算照度 $`emP Hel  
5. 使用PutWorkspaceData发送照度数据到Matlab u(s/4Lu  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ZE*m;  
7. 用Matlab画出照度数据 xD(JkOne  
8. 在Matlab计算照度平均值 BWct0=  
9. 返回数据到FRED中 Q6G-`&5
