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。 $@{ d\@U  
"3 2Ua3m:G  
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: ~9!@BL\  
enableservice('AutomationServer', true) It3@ Cd>  
enableservice('AutomationServer') vqUYr  
^Bw"+6d  
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。 U[yA`7Zs}  
Gyi0SM6v5&  
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: Vfq-H/+  
1. 在FRED脚本编辑界面找到参考. 7PfNPz<4+  
2. 找到Matlab Automation Server Type Library g p|G q  
3. 将名字改为MLAPP hQzT =0  
3,#qt}8`  
YyYp-0#  
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。 Rdj3dg'<

现在将脚本代码公布如下,此脚本执行如下几个步骤: _iqaKYT$  
1. 创建Matlab服务器。 |l|$ Q;  
2. 移动探测面对于前一聚焦面的位置。 <[gN4x>'  
3. 在探测面追迹光线 Y?oeP^V'u  
4. 在探测面计算照度 :W-xsw  
5. 使用PutWorkspaceData发送照度数据到Matlab ] :](xW%  
6. 使用PutFullMatrix发送标量场数据到Matlab中 .UK`~17!  
7. 用Matlab画出照度数据 9j;!4AJ1t  
8. 在Matlab计算照度平均值 Xe ^NVF  
9. 返回数据到FRED中 Fkqw #s(T
