[推荐]FRED案例-FRED如何调用Matlab [复制链接]

s2Z'_rT  
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。 5 [GdFd>{  
qQ&=Z`p!  
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： `$PdI4~J  
enableservice('AutomationServer', true) ]A?(OA  
    enableservice('AutomationServer') xUW\P$  
>X@4wP7l  
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。 GZefeBi

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： ;H' ,PjU  
1. 在FRED脚本编辑界面找到参考. ys/U.e|)!  
2. 找到Matlab Automation Server Type Library PiwMl)E|!  
    3. 将名字改为MLAPP

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。 j.]ln}b/'+

现在将脚本代码公布如下，此脚本执行如下几个步骤： O#_\@f#[  
1. 创建Matlab服务器。 A!$;pwn0  
2. 移动探测面对于前一聚焦面的位置。 QBYY1)6S,  
3. 在探测面追迹光线 iFOa9!_0n  
4. 在探测面计算照度 R+*-i+]Q#7  
5. 使用PutWorkspaceData发送照度数据到Matlab gB<1;_KW  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u+;iR/  
7. 用Matlab画出照度数据 Nf5zQ@o_y  
8. 在Matlab计算照度平均值 +@^FUt=tq  
9. 返回数据到FRED中 u5.zckV
