[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。 '4PAH2&n  

Tct[0B  
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： Oeo:
V"  
enableservice('AutomationServer', true) )" H$1  
enableservice('AutomationServer') A>"v1W
k  
Zk+J=Cwq}  
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。 ILt95l

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： x4SI TY  
1. 在FRED脚本编辑界面找到参考. *}9i@DP1,  
2. 找到Matlab Automation Server Type Library 20hF2V  
3. 将名字改为MLAPP gf!hO$sQ3

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。 ?Gq'r2V

1. 创建Matlab服务器。 m`<Mzk.u<

3. 在探测面追迹光线 eSZS`(#!(  
4. 在探测面计算照度 Jji~MiMn  
5. 使用PutWorkspaceData发送照度数据到Matlab e&dE>m  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ; 6Wlu3I  
7. 用Matlab画出照度数据 C24[brf
