[技术]FRED如何调用Matlab [复制链接]

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。 =CWc`  
u}^a^B$  
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： u<$S>  
enableservice('AutomationServer', true) A{G5Plrh  
enableservice('AutomationServer') lp?i_p/z  
7k.d|<mRv  
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。  F|DR

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： f34_?F<h  
1. 在FRED脚本编辑界面找到参考. zuK/(qZ  
2. 找到Matlab Automation Server Type Library d&O'r[S  
3. 将名字改为MLAPP =PI^X\if88

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。 [c,

现在将脚本代码公布如下，此脚本执行如下几个步骤： 3WQRN_  
1. 创建Matlab服务器。 ,R7=]~<io"  
2. 移动探测面对于前一聚焦面的位置。 er&uC4Y]a  
3. 在探测面追迹光线 Y{+zg9L*  
4. 在探测面计算照度 =>gyc;{2K<  
5. 使用PutWorkspaceData发送照度数据到Matlab EGp~Vo-  
6. 使用PutFullMatrix发送标量场数据到Matlab中 aeN}hG  
7. 用Matlab画出照度数据 yBpW#1=  
8. 在Matlab计算照度平均值 W@R$'r,@O  
9. 返回数据到FRED中 rD:gN%B=
