[技术]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。 iCXKi7  
2WF7^$^:  
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： md S`nhb  
enableservice('AutomationServer', true) "~+?xke5z  
enableservice('AutomationServer') ))NiX^)8^  
-5X*y4#  
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。 _+=M)lPm

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： oEJYAKN  
1. 在FRED脚本编辑界面找到参考. oj$^87KX  
2. 找到Matlab Automation Server Type Library 09_5niaz[  
3. 将名字改为MLAPP SSrYFu"

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。 %D_pTD\

现在将脚本代码公布如下，此脚本执行如下几个步骤： N"k IQe*}1  
1. 创建Matlab服务器。 V7}3H2]^  
2. 移动探测面对于前一聚焦面的位置。 XLq%nVBM8\  
3. 在探测面追迹光线 t
^')ST  
4. 在探测面计算照度 99/`23YL  
5. 使用PutWorkspaceData发送照度数据到Matlab

6. 使用PutFullMatrix发送标量场数据到Matlab中 ,GVD.whUl  
7. 用Matlab画出照度数据 Xg^9k00C  
8. 在Matlab计算照度平均值 #]vs*Sz  
9. 返回数据到FRED中 $C^tZFq
