[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。 D;C5,rNt  
J/[7d?hI/  
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： hg&u0AQ2  
enableservice('AutomationServer', true) j
rcc  
enableservice('AutomationServer') !7Uu]m69n  
+gNX7xuY  
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。 %IU4\ZY>

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： 2%]t3\XW  
1. 在FRED脚本编辑界面找到参考. 8J^d7uC  
2. 找到Matlab Automation Server Type Library W U0UG$o`  
3. 将名字改为MLAPP w= B

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。 _KxX&THaj

现在将脚本代码公布如下，此脚本执行如下几个步骤： PbQE{&D#  
1. 创建Matlab服务器。 'Ye]eL,I\  
2. 移动探测面对于前一聚焦面的位置。 <L%HG  
3. 在探测面追迹光线 P;>!wU~*  
4. 在探测面计算照度 /rOnm=P+Q  
5. 使用PutWorkspaceData发送照度数据到Matlab +>^[W~[2  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Ltl]j*yei  
7. 用Matlab画出照度数据 \CDAFu#  
8. 在Matlab计算照度平均值 nD

9. 返回数据到FRED中 'l8eH$
