[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。 PRah?|*0s  
SQ1&n;M}f  
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： r2Z`4tN:  
enableservice('AutomationServer', true) vCmh3TQ  
enableservice('AutomationServer') eD(a +El}  
Y zvtxX*  
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。 R;.WOies4

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： 2mT+@G  
1. 在FRED脚本编辑界面找到参考. 7r;A wa  
2. 找到Matlab Automation Server Type Library plIx""a^h  
3. 将名字改为MLAPP AdYQhF##

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。 X'F$K!o*,:

现在将脚本代码公布如下，此脚本执行如下几个步骤： UCWU|r<s,  
1. 创建Matlab服务器。 yTvK)4&  
2. 移动探测面对于前一聚焦面的位置。 Oxvw`a#  
3. 在探测面追迹光线 $.cGRz
 
4. 在探测面计算照度 3gh^a;uC  
5. 使用PutWorkspaceData发送照度数据到Matlab N}h%8\  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ;$/G T
 
7. 用Matlab画出照度数据 n)H0;25L  
8. 在Matlab计算照度平均值 '

9. 返回数据到FRED中 Bx)&MYY}[[
