[推荐]FRED案例-FRED如何调用Matlab [复制链接]

ytDp 4x<W)  
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。 c; MF

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： ask76  e  
enableservice('AutomationServer', true) <*Ex6/j  
    enableservice('AutomationServer') {hNvCk  
#^] v5s  
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。 =_"[ &^

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： 0DZ}8"2  
1. 在FRED脚本编辑界面找到参考. Q4[^JQsR2  
2. 找到Matlab Automation Server Type Library 4g%BCGsys  
    3. 将名字改为MLAPP #Bih=A #

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。 iPuX

现在将脚本代码公布如下，此脚本执行如下几个步骤： 7gx 7NDt  
1. 创建Matlab服务器。 'f "KV|  
2. 移动探测面对于前一聚焦面的位置。 L3@upb  
3. 在探测面追迹光线 .^F(&c*['  
4. 在探测面计算照度 4[.DQ#r  
5. 使用PutWorkspaceData发送照度数据到Matlab Pw:{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 f)b+>!  
7. 用Matlab画出照度数据 -,Oq=w*EV  
8. 在Matlab计算照度平均值 2BGS$$pP  
9. 返回数据到FRED中 &hSABtr}
