[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。 p=V (_  
7g[T#B'/x,  
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： f =B)jYI  
enableservice('AutomationServer', true) ^W{+?q'  
enableservice('AutomationServer') KFvNsqd  
xQT`sK+  
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。 TU&gj1

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： 615, P/  
1. 在FRED脚本编辑界面找到参考. Tl6%z9rY@  
2. 找到Matlab Automation Server Type Library t 5g@t0$  
3. 将名字改为MLAPP % V/J6

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。 p(fYpD

3. 在探测面追迹光线 L}7c{6!F7  
4. 在探测面计算照度 X`YAJG  
5. 使用PutWorkspaceData发送照度数据到Matlab rZm|7A)i  
6. 使用PutFullMatrix发送标量场数据到Matlab中 c;

7. 用Matlab画出照度数据 : z*OAl"
