[推荐]FRED案例-FRED如何调用Matlab [复制链接]

jn5=N[hd  
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。 2- |

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： 4#'^\5  
enableservice('AutomationServer', true) YGZAtSf3z  
    enableservice('AutomationServer') HfZ (U5~  
TZ`]#^kU  
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。 : .UX[!^  
o} bj!h]N  
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： &?uzJx~  
1. 在FRED脚本编辑界面找到参考. ?45K%;.9Q  
2. 找到Matlab Automation Server Type Library -jklH/gF\%  
    3. 将名字改为MLAPP 2={K-s20

     B7x"ef  
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。 #o}{cXX#

1. 创建Matlab服务器。 =Un6|]  
2. 移动探测面对于前一聚焦面的位置。 d}^:E  
3. 在探测面追迹光线 SFm.<^6  
4. 在探测面计算照度 qH}62DP3  
5. 使用PutWorkspaceData发送照度数据到Matlab r4z}yt+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {0m[:af&  
7. 用Matlab画出照度数据 B'[3kJ'  
8. 在Matlab计算照度平均值 )H=[NB6J8  
9. 返回数据到FRED中 B@~eBU,$
