[分享]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。 3:[!t%Yb  
6kt]`H`cfJ  
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： 1mJbQ#5  
enableservice('AutomationServer', true) G;(onJz  
enableservice('AutomationServer') m<FF$pTT  
M`0(!Q}  
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。 L]k*QIn:h

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： r0F_;  
1. 在FRED脚本编辑界面找到参考. [AXsnpa/C  
2. 找到Matlab Automation Server Type Library bnijM/73  
3. 将名字改为MLAPP =m`l%V[

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。 fd4;mc1T

现在将脚本代码公布如下，此脚本执行如下几个步骤： k_]\(myq  
1. 创建Matlab服务器。 Q"A_bdg5  
2. 移动探测面对于前一聚焦面的位置。 ucw`;<d8  
3. 在探测面追迹光线 p` $fTgm  
4. 在探测面计算照度 s4(Wp3>3i  
5. 使用PutWorkspaceData发送照度数据到Matlab nt7|f,_J  
6. 使用PutFullMatrix发送标量场数据到Matlab中 C?,*U  
7. 用Matlab画出照度数据 Tj=gRQ2v  
8. 在Matlab计算照度平均值 '}_=kp'X  
9. 返回数据到FRED中 yKYl@&H/%
