[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。 xQ?>72grP  
A#uU]S  
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： w$gvgz  
enableservice('AutomationServer', true) e r" w{  
enableservice('AutomationServer') \lL[08G  
y48]|%73  
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。 Nk~}aj

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： owVvbC2<b(  
1. 在FRED脚本编辑界面找到参考. \j)Evjw  
2. 找到Matlab Automation Server Type Library J )1  
3. 将名字改为MLAPP vwR_2u

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。 _sjS'*]

现在将脚本代码公布如下，此脚本执行如下几个步骤： DF%d/a{]  
1. 创建Matlab服务器。 I-v} DuM  
2. 移动探测面对于前一聚焦面的位置。  ` Xc7b  
3. 在探测面追迹光线 VA/2$5Wu  
4. 在探测面计算照度 5f0M{J,KC  
5. 使用PutWorkspaceData发送照度数据到Matlab :]"5UY?oF  
6. 使用PutFullMatrix发送标量场数据到Matlab中 4^_6~YP7  
7. 用Matlab画出照度数据 ,CE/o7.FG  
8. 在Matlab计算照度平均值 =4ygbk  
9. 返回数据到FRED中 LPs%^*8(2
