[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。 {4_s:+v0  
a (U52dO,  
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： 3.W[]zH/u  
enableservice('AutomationServer', true) !}Xoqamm  
enableservice('AutomationServer') u\LNJo| B  
pRQ7rT',v  
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。 fHiL%]z

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：  3IxC@QR  
1. 在FRED脚本编辑界面找到参考. \,S|>CPQ  
2. 找到Matlab Automation Server Type Library ~n=DI/AJ@-  
3. 将名字改为MLAPP a1pp=3Pd?~

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。 I\*6 >

1. 创建Matlab服务器。 X>I3N?5  
2. 移动探测面对于前一聚焦面的位置。 luP;P&  
3. 在探测面追迹光线 'TeH(?3G  
4. 在探测面计算照度 py;p7y!gxA  
5. 使用PutWorkspaceData发送照度数据到Matlab Gz&}OO  
6. 使用PutFullMatrix发送标量场数据到Matlab中 2^[dy>[y0
