[推荐]FRED案例-FRED如何调用Matlab [复制链接]

@ioJ]$o7  
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。 xml7Uarc  
,Vm < rK  
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： 50wulGJud  
enableservice('AutomationServer', true)
}?i0 I  
    enableservice('AutomationServer') !hy-L_wL]  
_Y4` xv0/  
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。 pa3{8x{9m

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： n'LrQU  
1. 在FRED脚本编辑界面找到参考. q:0N<$63  
2. 找到Matlab Automation Server Type Library KYI/  
    3. 将名字改为MLAPP o[w:1q7

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。 p)-^;=<B3

现在将脚本代码公布如下，此脚本执行如下几个步骤： ]Q1yNtN  
1. 创建Matlab服务器。 %)1?TU  
2. 移动探测面对于前一聚焦面的位置。 M FMs[+2_o  
3. 在探测面追迹光线 3(N$nsi  
4. 在探测面计算照度 U9 s&  
5. 使用PutWorkspaceData发送照度数据到Matlab &PHTpkaam  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {\1?ZrCI&  
7. 用Matlab画出照度数据 bsli0FJSh'  
8. 在Matlab计算照度平均值 $8h%a 8I  
9. 返回数据到FRED中 G>}255qY
