[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。 wr@GN8e`  
D=w9cKa  
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： Z% Z"VoxH  
enableservice('AutomationServer', true) 5!:._TcO  
enableservice('AutomationServer') sQ(1/"gb  
j6X LyeG7  
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。 Qg>L,ZO

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： 3Wj,}  
1. 在FRED脚本编辑界面找到参考. U2&HSE|2J  
2. 找到Matlab Automation Server Type Library B007x{-L  
3. 将名字改为MLAPP ZKsQ2"8{M  
CveWl$T12  
q6)p*}-  
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。 )_pt*xo

现在将脚本代码公布如下，此脚本执行如下几个步骤： '^lUL) R  
1. 创建Matlab服务器。 \6c8z/O7   
2. 移动探测面对于前一聚焦面的位置。 `Of[{.Q  
3. 在探测面追迹光线 ,# iZS&  
4. 在探测面计算照度 U$@83?O{iM  
5. 使用PutWorkspaceData发送照度数据到Matlab b60[({A\s&  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?7rD42\8H  
7. 用Matlab画出照度数据 G*Ib^;$u  
8. 在Matlab计算照度平均值 09x+Tko9;*  
9. 返回数据到FRED中 p9w%kM?
