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。 -/?<@*n  
B/}>UHM  
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: {D#`+uw  
enableservice('AutomationServer', true) B:.rp.1   
enableservice('AutomationServer') s9>!^MzBK  
TQH#sx  
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。 S\(_"xJPp  
m ws.)  
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: g7-K62bb  
1. 在FRED脚本编辑界面找到参考. 4r&~=up]  
2. 找到Matlab Automation Server Type Library 2B;QS\e"  
3. 将名字改为MLAPP E .5xzY

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。 (0S7

现在将脚本代码公布如下,此脚本执行如下几个步骤: ~O6=dR  
1. 创建Matlab服务器。 `314.a6S  
2. 移动探测面对于前一聚焦面的位置。 r.5F^   
3. 在探测面追迹光线 Viw3 /K  
4. 在探测面计算照度 `RRORzXoS  
5. 使用PutWorkspaceData发送照度数据到Matlab `0F IJT  
6. 使用PutFullMatrix发送标量场数据到Matlab中 '-=?lyKv  
7. 用Matlab画出照度数据 rv:O|wZ  
8. 在Matlab计算照度平均值 $)!Z"2T  
9. 返回数据到FRED中 ?a@l.ZM*
