[分享]FRED如何调用Matlab [复制链接]

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。 L$}'6y/@  
!)uXCg9U  
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： C] |m|`  
enableservice('AutomationServer', true) 5K|s]Y;  
enableservice('AutomationServer') Oz.Zxw  
'h{DjNSM  
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。 #M8>

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： O9)k)A]`O  
1. 在FRED脚本编辑界面找到参考. aGmbB7[BZ  
2. 找到Matlab Automation Server Type Library i-&"1D[&  
3. 将名字改为MLAPP "'6R|<u=:

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。 W7 9.,#

现在将脚本代码公布如下，此脚本执行如下几个步骤： K#plSD^f=  
1. 创建Matlab服务器。 @#| R{5=+  
2. 移动探测面对于前一聚焦面的位置。 IV$2`)[A&X  
3. 在探测面追迹光线 OY(znVHU  
4. 在探测面计算照度 n`7n5M*  
5. 使用PutWorkspaceData发送照度数据到Matlab 7>|p_o`e  
6. 使用PutFullMatrix发送标量场数据到Matlab中 u5dyhx7  
7. 用Matlab画出照度数据 IR*:i{  
8. 在Matlab计算照度平均值 \ffU15@N  
9. 返回数据到FRED中 }i2dXC/
