[推荐]FRED案例-FRED如何调用Matlab [复制链接]

`2 vv8cg^  
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。 qTG

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： *2$I, ~(P  
enableservice('AutomationServer', true) "F,d}3}  
    enableservice('AutomationServer') d"7l<y5  
C2~t  
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。 h^u 9W7.

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： 3EM=6\#q  
1. 在FRED脚本编辑界面找到参考. 3Pb]Of#  
2. 找到Matlab Automation Server Type Library \xQ10\u  
    3. 将名字改为MLAPP M.h)]S>

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。 qyfw$$X

现在将脚本代码公布如下，此脚本执行如下几个步骤： tkN5|95  
1. 创建Matlab服务器。 ypoJ4EZ(  
2. 移动探测面对于前一聚焦面的位置。 B&tU~  
3. 在探测面追迹光线 0a#2Lo  
4. 在探测面计算照度 t-xw=&!w  
5. 使用PutWorkspaceData发送照度数据到Matlab hkSK;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *?k~n9n5U  
7. 用Matlab画出照度数据 Lyx \s;  
8. 在Matlab计算照度平均值 :/Zy=F9:  
9. 返回数据到FRED中 t+R8{9L-
