[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。 i@q&5;%%  
~rm_vo  
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： *v`eUQ:  
enableservice('AutomationServer', true) jo7\`#(Q  
enableservice('AutomationServer')
0"R|..l/  
:]"V-1#}  
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。 ]iWRo'

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： FwK]$4*  
1. 在FRED脚本编辑界面找到参考. *Ly6`HZ9  
2. 找到Matlab Automation Server Type Library rA1._   
3. 将名字改为MLAPP SJLis"8

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。 [Pp'Ye~K@c

现在将脚本代码公布如下，此脚本执行如下几个步骤： "4Nt\WQ  
1. 创建Matlab服务器。 pCDmXB

6. 使用PutFullMatrix发送标量场数据到Matlab中 #4:?gfIj  
7. 用Matlab画出照度数据 Sdo-nt
