[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。 0xH&^Ia1B

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： XB]>Z)  
enableservice('AutomationServer', true) a,
h]DkD  
enableservice('AutomationServer') y"k%Wa`*  
 |CAMd
U  
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。 T1%}H3

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： T(Ji%S>  
1. 在FRED脚本编辑界面找到参考. 6?

2. 找到Matlab Automation Server Type Library +Jm[IN

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。 tT+W>oA/M

1. 创建Matlab服务器。 YMVmpcz  
2. 移动探测面对于前一聚焦面的位置。 3R)|DGql=1  
3. 在探测面追迹光线 '(-H#D.oy'  
4. 在探测面计算照度 Y@7n>U  
5. 使用PutWorkspaceData发送照度数据到Matlab @"H7Q1Hg!*  
6. 使用PutFullMatrix发送标量场数据到Matlab中 1jE {]/Y7&  
7. 用Matlab画出照度数据 #Jt1AV  
8. 在Matlab计算照度平均值 H;0K4|I  
9. 返回数据到FRED中 @>&b&uj7T
