[推荐]FRED案例-FRED如何调用Matlab [复制链接]

K_Y-N!h  
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。 d^=BXCoC  
,H7X_KbFD4  
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： 4pmeu:26  
enableservice('AutomationServer', true) oO}g~<fYG  
    enableservice('AutomationServer') r>mBe;[TX  
_,3ljf?WQM  
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]\

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： DE13x*2  
1. 在FRED脚本编辑界面找到参考. -@Ap;,=  
2. 找到Matlab Automation Server Type Library |x[I!I7.F  
    3. 将名字改为MLAPP 3:nhZN/95T

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。 _[:6.oNjIe

现在将脚本代码公布如下，此脚本执行如下几个步骤： LKN7Lkl  
1. 创建Matlab服务器。 manw;`Q  
2. 移动探测面对于前一聚焦面的位置。 `IHP_IfR  
3. 在探测面追迹光线 D?Oe";"/  
4. 在探测面计算照度 .
:_'l)-  
5. 使用PutWorkspaceData发送照度数据到Matlab pyEQb#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 EEe$A?a;  
7. 用Matlab画出照度数据 %0\@\fC41  
8. 在Matlab计算照度平均值 Bc>j5^)8w  
9. 返回数据到FRED中 Y;w|Fvjj+
