FRED案例-FRED如何调用Matlab

9?q ^yy  
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。 :%gM Xsb  
Kum" }ux  
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: <*I*#WI&B  
enableservice('AutomationServer', true) G6}!PEwM  
    enableservice('AutomationServer') r $[{sW  
ay =B<|!  
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。 vmv6y*qU  
@Gw.U>"!C  
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: r0wAh/J|  
1. 在FRED脚本编辑界面找到参考. M6ZXq6J  
2. 找到Matlab Automation Server Type Library XqU0AbQ  
    3. 将名字改为MLAPP DR @yd,  
     2%v6h  
     8>G5VhCm~o  
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。 F >H\F@Wl

现在将脚本代码公布如下,此脚本执行如下几个步骤: uGn BlR$}  
1. 创建Matlab服务器。 H ?eG5  
2. 移动探测面对于前一聚焦面的位置。 $> ;|  
3. 在探测面追迹光线 }+}Cl T  
4. 在探测面计算照度 .AQTUd(_  
5. 使用PutWorkspaceData发送照度数据到Matlab h@]{j_$u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )Y&B63]B  
7. 用Matlab画出照度数据 E^Ch;)j|  
8. 在Matlab计算照度平均值 W0;QufV  
9. 返回数据到FRED中 Xq_h C"s
