[推荐]FRED案例-FRED如何调用Matlab [复制链接]

)< &B&Hp  
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。 rC* sNy2  
61ON  
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： ]}UeuF\  
enableservice('AutomationServer', true) >!:$@!6L  
    enableservice('AutomationServer') ,6S_&<{  
i}v}K'`  
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。 34/]m/2NZK

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： oi33{#%t  
1. 在FRED脚本编辑界面找到参考. +1E?He:iQ  
2. 找到Matlab Automation Server Type Library GoGohsj  
    3. 将名字改为MLAPP +0oyt?

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。 Tx|SAa=V

现在将脚本代码公布如下，此脚本执行如下几个步骤： GFASF,+  
1. 创建Matlab服务器。 :,xyVb+  
2. 移动探测面对于前一聚焦面的位置。 WI*^+E&=*  
3. 在探测面追迹光线 t1.zWe+C>3  
4. 在探测面计算照度 $M

5. 使用PutWorkspaceData发送照度数据到Matlab pXpLL

    6. 使用PutFullMatrix发送标量场数据到Matlab中 twYB=68  
7. 用Matlab画出照度数据 al3BWRq'f  
8. 在Matlab计算照度平均值 GY0XWUlC  
9. 返回数据到FRED中 Z>>gXh<e[
