[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。 BG|

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： _(zZrUHB  
enableservice('AutomationServer', true) xU/7}='T  
enableservice('AutomationServer') rp9?p%  
:V3z`}Rl  
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。 nw4I<Q

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： :Kmn

1. 在FRED脚本编辑界面找到参考. 44NMof8N  
2. 找到Matlab Automation Server Type Library HQvJ*U4++  
3. 将名字改为MLAPP GO?hB4 9T

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。 lihIPMU

现在将脚本代码公布如下，此脚本执行如下几个步骤： _ amP:h  
1. 创建Matlab服务器。 6r|=^3{  
2. 移动探测面对于前一聚焦面的位置。 Y-UXr8  
3. 在探测面追迹光线 {E; bT|3z  
4. 在探测面计算照度 @Jx1n Q^  
5. 使用PutWorkspaceData发送照度数据到Matlab bwM?DY
 
6. 使用PutFullMatrix发送标量场数据到Matlab中 MaPOmS8?  
7. 用Matlab画出照度数据 #f [}a  
8. 在Matlab计算照度平均值 @U3:9~Q  
9. 返回数据到FRED中 E!'6vDVC:
