[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。 hQl3F6-ud  
- n11L  
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： D97oS!*  
enableservice('AutomationServer', true) rD<@$KpP  
enableservice('AutomationServer') VA2%2g2n{  
o.Q|%&1  
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。 >JC.qjA

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：  h}+,]^  
1. 在FRED脚本编辑界面找到参考. $WTu7lVV[1  
2. 找到Matlab Automation Server Type Library ~v+& ?dg  
3. 将名字改为MLAPP / ^!(rHf  
BflF*-s ^  
d \0K3=h  
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。 3(vI{[yhT

现在将脚本代码公布如下，此脚本执行如下几个步骤： ;~/  
1. 创建Matlab服务器。 ^$rt|]  
2. 移动探测面对于前一聚焦面的位置。 \ m2[  
3. 在探测面追迹光线 #T !YFMh;  
4. 在探测面计算照度 )"j_NlO  
5. 使用PutWorkspaceData发送照度数据到Matlab 1a#wUd3  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Vs9fAAXS4  
7. 用Matlab画出照度数据 Q"QrbU  
8. 在Matlab计算照度平均值 S}*#$naK  
9. 返回数据到FRED中 nLo:\I(
