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。 `p#u9M>  
$aC%&&+wG  
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: -Pp =)_O  
enableservice('AutomationServer', true) 6[T)Q^0`  
enableservice('AutomationServer') MA+{7 [  
p)c"xaTP#F  
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。 n2N:rP  
'GF<_3I2l  
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: k=  
1. 在FRED脚本编辑界面找到参考. ' JAcN@q~z  
2. 找到Matlab Automation Server Type Library [A'9sxG  
3. 将名字改为MLAPP m?y'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。 }JM02R~I

现在将脚本代码公布如下,此脚本执行如下几个步骤: +![\7  
1. 创建Matlab服务器。 4"et4Y7  
2. 移动探测面对于前一聚焦面的位置。 F*_ytL  
3. 在探测面追迹光线 \Lz4ZZjSY  
4. 在探测面计算照度 a=r^?q'/  
5. 使用PutWorkspaceData发送照度数据到Matlab yv(\5)XF  
6. 使用PutFullMatrix发送标量场数据到Matlab中 *?R<gWCF  
7. 用Matlab画出照度数据 &eFv~9  
8. 在Matlab计算照度平均值 +i(;@% kv  
9. 返回数据到FRED中 D.,~I^W
