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。 LIfQh  
^IgxzGD  
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: v x qsK  
enableservice('AutomationServer', true) N y_d  
enableservice('AutomationServer') $yG>=GN  
.Cq'D.  
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。 F+yu[Dh:

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: D@9adwQb  
1. 在FRED脚本编辑界面找到参考. l /?Jp+]  
2. 找到Matlab Automation Server Type Library fBtTJ+51}  
3. 将名字改为MLAPP -/ 5" Py

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。 D#VUx9kugv

现在将脚本代码公布如下,此脚本执行如下几个步骤: Zb> UY8  
1. 创建Matlab服务器。 4%k{vo5i  
2. 移动探测面对于前一聚焦面的位置。 )1#J4  
3. 在探测面追迹光线 tf1iRXf8  
4. 在探测面计算照度 `h%(ZG ~  
5. 使用PutWorkspaceData发送照度数据到Matlab v6uXik  
6. 使用PutFullMatrix发送标量场数据到Matlab中 f]c{,LFvZ  
7. 用Matlab画出照度数据 u!$+1fI>  
8. 在Matlab计算照度平均值 L\)GPTo!x  
9. 返回数据到FRED中 IIj :\?r
