[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。 (I'{ pF)  
{XUSw8W'  
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： 2;3&&yK2b  
enableservice('AutomationServer', true) YnW9uy5  
enableservice('AutomationServer') "a3
3m:]J  
[McqwU/Q  
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。 U>m{B|H

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： g)D@4RM  
1. 在FRED脚本编辑界面找到参考. 1uR@ZK  
2. 找到Matlab Automation Server Type Library {?EmO+![}  
3. 将名字改为MLAPP ; C(5lD&\5

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。 >K1e=SY

现在将脚本代码公布如下，此脚本执行如下几个步骤： ITi#p%  
1. 创建Matlab服务器。 ~ b66 ;  
2. 移动探测面对于前一聚焦面的位置。 RL/7>YQ  
3. 在探测面追迹光线 D`X<b4e8/  
4. 在探测面计算照度 8}4.x3uw  
5. 使用PutWorkspaceData发送照度数据到Matlab pY&dw4V  
6. 使用PutFullMatrix发送标量场数据到Matlab中 R!W
DQGR(2  
7. 用Matlab画出照度数据 d{@'&?tj  
8. 在Matlab计算照度平均值 JP {`

9. 返回数据到FRED中 @\xEK5SG
