[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。 w;k):;$  
f 1w~!O9  
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： (>`5z(X  
enableservice('AutomationServer', true) 8<.C3m 6h  
enableservice('AutomationServer') Cl^\OZN\=  
G 16!eDMt  
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。 qw@puw@D

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： u:m]CPz  
1. 在FRED脚本编辑界面找到参考. ,hq)1u  
2. 找到Matlab Automation Server Type Library BT)X8>ct  
3. 将名字改为MLAPP k]5Bykf`Ky

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。 S+'rG+NJ

现在将脚本代码公布如下，此脚本执行如下几个步骤： DyeQJ7p  
1. 创建Matlab服务器。 = M]iIWQ@`  
2. 移动探测面对于前一聚焦面的位置。 g.'yZvaP  
3. 在探测面追迹光线 ]8icBneA~'  
4. 在探测面计算照度 P(XaTU&-  
5. 使用PutWorkspaceData发送照度数据到Matlab 5B&;uY   
6. 使用PutFullMatrix发送标量场数据到Matlab中 F)
+{AQL  
7. 用Matlab画出照度数据 Pu"R,a  
8. 在Matlab计算照度平均值 p/U+0f  
9. 返回数据到FRED中 6B@CurgB
