[推荐]FRED案例-FRED如何调用Matlab [复制链接]

9T<x&  
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。 ]\

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： % >=!p  
enableservice('AutomationServer', true) ]
q4rlT.i  
    enableservice('AutomationServer') A0Qb5e  
\-g)T}g,I  
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。 z<Nfm

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rjE.+v  
1. 在FRED脚本编辑界面找到参考. .[_L=_.  
2. 找到Matlab Automation Server Type Library CB^U6ZS  
    3. 将名字改为MLAPP PUUwv_  
     $` ""  
     OGl}-kw  
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。 ~sh`r{

现在将脚本代码公布如下，此脚本执行如下几个步骤： j:v@p

1. 创建Matlab服务器。 ?{[ v+t#  
2. 移动探测面对于前一聚焦面的位置。 |!4K!_y  
3. 在探测面追迹光线 +{oG|r3L  
4. 在探测面计算照度 z:wutqru  
5. 使用PutWorkspaceData发送照度数据到Matlab wfH^<jY)E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 a^I\ /&aw'  
7. 用Matlab画出照度数据 " )1V]}+m  
8. 在Matlab计算照度平均值 ~nay"g:  
9. 返回数据到FRED中 .:F%_dS D
