[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。 4{|"7/PE1  
5\VWCI  
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： "E4a=YH_  
enableservice('AutomationServer', true) {]4LULq  
enableservice('AutomationServer') ]3Sp W{=^(  
inp7K41  
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。 I{=Qtnlb  
 o-B$J?  
在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： dioGAai'  
1. 在FRED脚本编辑界面找到参考. [v!f<zSQK  
2. 找到Matlab Automation Server Type Library G$('-3@i`w  
3. 将名字改为MLAPP kb!%-k

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。 SiN0OB

1. 创建Matlab服务器。 +D*Z_Yh6

3. 在探测面追迹光线 42ge3>  
4. 在探测面计算照度 .O<obq~;C  
5. 使用PutWorkspaceData发送照度数据到Matlab AbW6x  
6. 使用PutFullMatrix发送标量场数据到Matlab中 t4-[Z$n5  
7. 用Matlab画出照度数据 JC}D`h
