[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。 >5Lexj  
<y>:B}9'  
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： g:gB`8w?  
enableservice('AutomationServer', true) "l,UOv c  
enableservice('AutomationServer') g-@h>$< 1  
J_ J+cRwq  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 iZ;TYcT  
>.LKct*5K  
在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： @ yxt($G  
1. 在FRED脚本编辑界面找到参考. Ze ? g  
2. 找到Matlab Automation Server Type Library ~FUa:KYD  
3. 将名字改为MLAPP Kt `

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。 2p:r`THvS5

现在将脚本代码公布如下，此脚本执行如下几个步骤： QnK
C#   
1. 创建Matlab服务器。 EOVZGZF  
2. 移动探测面对于前一聚焦面的位置。 r4eUZ .8R  
3. 在探测面追迹光线 9?`RR/w  
4. 在探测面计算照度 qm(1:iK,0  
5. 使用PutWorkspaceData发送照度数据到Matlab rsF:4G"%  
6. 使用PutFullMatrix发送标量场数据到Matlab中 i_U}{|j  
7. 用Matlab画出照度数据 nNn56&N]  
8. 在Matlab计算照度平均值 (0jr;jv  
9. 返回数据到FRED中 Vxh.<b6&'
