[推荐]FRED案例-FRED如何调用Matlab [复制链接]

K@=u F1?  
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。 6Tmz!E0  
-}<Ru)  
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： a%c 
<3'  
enableservice('AutomationServer', true) By6O@ .\V  
    enableservice('AutomationServer') _}[WX[Le{  
M <JX  
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。 <6-73LsHcP

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： 5nib<B%<V  
1. 在FRED脚本编辑界面找到参考. 0B8Wf/j?M  
2. 找到Matlab Automation Server Type Library S8AbLl9G@>  
    3. 将名字改为MLAPP =LLpJ+

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(RKAFjY

现在将脚本代码公布如下，此脚本执行如下几个步骤： K

1. 创建Matlab服务器。 u\ 7Y_`8  
2. 移动探测面对于前一聚焦面的位置。 [?N,3  
3. 在探测面追迹光线 T"htWo{v>  
4. 在探测面计算照度 ;5;>f)diS  
5. 使用PutWorkspaceData发送照度数据到Matlab c[2ikI,n[  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 'V%w{ZiiV  
7. 用Matlab画出照度数据 CC^]Y.9  
8. 在Matlab计算照度平均值 C+t3a@&|  
9. 返回数据到FRED中 Y.I~.66s
