[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。 a&_h(  
5!F;|*vC8  
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： U=G49~E  
enableservice('AutomationServer', true) ",b:rgpRp  
enableservice('AutomationServer') bgorW"'  
m;dwt1'Zw  
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。 X`D2w:

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： oN1D&*  
1. 在FRED脚本编辑界面找到参考. +yP!7]  
2. 找到Matlab Automation Server Type Library BD C DQ

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。 "|8oFf)l@B

1. 创建Matlab服务器。 4EqThvI{  
2. 移动探测面对于前一聚焦面的位置。 }emUpju<C  
3. 在探测面追迹光线 {fXkbMO|  
4. 在探测面计算照度 vXDs/,`r  
5. 使用PutWorkspaceData发送照度数据到Matlab <VxA&bb7c  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ^~H}N$W"-q  
7. 用Matlab画出照度数据 KO
