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。 VxkCK02k  
u0bfX,e2U  
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: &dhcKO<4  
enableservice('AutomationServer', true) bH\'uaJ  
enableservice('AutomationServer') 99l>CYXd  
P+)qE6\  
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。 W>5vRwx00  
AW,v  
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: 3I9T|wQ-]  
1. 在FRED脚本编辑界面找到参考. |^7f\.oF  
2. 找到Matlab Automation Server Type Library HE#,(;1i  
3. 将名字改为MLAPP h4hN1<ky\  
g$*/ XSr(  
EJf#f  
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。 Vq3gceo'0A

现在将脚本代码公布如下,此脚本执行如下几个步骤: ~7dM!g{W  
1. 创建Matlab服务器。 r\$6'+Si  
2. 移动探测面对于前一聚焦面的位置。 "w}-?:# j  
3. 在探测面追迹光线 +h0PR?  
4. 在探测面计算照度  9R9__w;  
5. 使用PutWorkspaceData发送照度数据到Matlab {>8Pl2J  
6. 使用PutFullMatrix发送标量场数据到Matlab中 S~KS9E~\  
7. 用Matlab画出照度数据 j$3rJA%rN  
8. 在Matlab计算照度平均值 FJP< bREQ  
9. 返回数据到FRED中 D Irgq|8
