FRED案例-FRED如何调用Matlab

+lVA$]d  
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。 "M[&4'OM  
L97 ~ma  
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: "-X8  
enableservice('AutomationServer', true) d4^x,hzV  
    enableservice('AutomationServer') |%ZJN{!R  
A/UOcl+N  
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。 <;?1#ok

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: m;>G]Sbe  
1. 在FRED脚本编辑界面找到参考. n^l*oEl  
2. 找到Matlab Automation Server Type Library "a~r'+'<  
    3. 将名字改为MLAPP $%"hhju  
      ,Zb  
     Ay 4P_>^  
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。 k+P3z&e

现在将脚本代码公布如下,此脚本执行如下几个步骤: D]}~`SO  
1. 创建Matlab服务器。 fmQif]J;;  
2. 移动探测面对于前一聚焦面的位置。 )8#-IXxp  
3. 在探测面追迹光线 myN2G?>;  
4. 在探测面计算照度 sZr \mQ~  
5. 使用PutWorkspaceData发送照度数据到Matlab fjy\Q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ZX`x9/0&  
7. 用Matlab画出照度数据 D86F5HT}}  
8. 在Matlab计算照度平均值 3%GsTq2o  
9. 返回数据到FRED中 -.M J3
