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。 =.9tRq  
hiaTJE|J?  
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: Bv`3T Af2  
enableservice('AutomationServer', true) /jOug>s  
enableservice('AutomationServer') ^Ux*"\/Es  
UZE%!OWpeK  
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。 > 'JWW*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: o2LUB)=R'  
1. 在FRED脚本编辑界面找到参考. $U%N$_k?  
2. 找到Matlab Automation Server Type Library @2 SL$0!QA  
3. 将名字改为MLAPP ~ o5h}OU"

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。 ||4++84{

现在将脚本代码公布如下,此脚本执行如下几个步骤: r}t%DH  
1. 创建Matlab服务器。 hhOrO<(  
2. 移动探测面对于前一聚焦面的位置。 3. g-V  
3. 在探测面追迹光线 ?^: xNRE$j  
4. 在探测面计算照度 kC+dQ&@g{  
5. 使用PutWorkspaceData发送照度数据到Matlab .eDI ZX  
6. 使用PutFullMatrix发送标量场数据到Matlab中 }5ONDg(I~  
7. 用Matlab画出照度数据 [m]O^Hp{{  
8. 在Matlab计算照度平均值 i)d'l<RA  
9. 返回数据到FRED中 ;p)fW/<
