[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。 )WsR 8tk  
J+l#!gk$!  
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： Oar%LSkPRz  
enableservice('AutomationServer', true) 4"#F=f0  
enableservice('AutomationServer') &Xi]0\M)  
~~}8D"  
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>ZU67-

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： 9F7}1cH7g@  
1. 在FRED脚本编辑界面找到参考. >OKc\m2%Q  
2. 找到Matlab Automation Server Type Library 4@=[rZb9  
3. 将名字改为MLAPP y(X^wC

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。 YM#J_sy@J.

现在将脚本代码公布如下，此脚本执行如下几个步骤： X0]Se(  
1. 创建Matlab服务器。 ?dmwz4k0  
2. 移动探测面对于前一聚焦面的位置。 )3^#C

3. 在探测面追迹光线 )kIjZ  
4. 在探测面计算照度 ro8C^d]  
5. 使用PutWorkspaceData发送照度数据到Matlab BC R]K  
6. 使用PutFullMatrix发送标量场数据到Matlab中 +de5y]1H,|  
7. 用Matlab画出照度数据 [a7S?%>Bh  
8. 在Matlab计算照度平均值 A>6_h1  
9. 返回数据到FRED中 b6g/SIae
