[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。 FDHW'OP4
 
.sMs_ 5D  
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： z>x@o}#u\|  
enableservice('AutomationServer', true) 8@3K, [Mo  
enableservice('AutomationServer') Z;0~f<e%  
7& M-^Ev  
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。 \Mf>X\}

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： q=1 N&#RG  
1. 在FRED脚本编辑界面找到参考. )rc!irac]  
2. 找到Matlab Automation Server Type Library m]p{]6h  
3. 将名字改为MLAPP B#sCB&(

GES}o9?#  
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。 z;OYPGvkw

现在将脚本代码公布如下，此脚本执行如下几个步骤： Fs+tcr/\[  
1. 创建Matlab服务器。 ou,[0B3n0  
2. 移动探测面对于前一聚焦面的位置。 aSR-.r  
3. 在探测面追迹光线 U,P_bz*)  
4. 在探测面计算照度 b@CB +8$  
5. 使用PutWorkspaceData发送照度数据到Matlab XLh)$rZ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 9A.RD`fg  
7. 用Matlab画出照度数据 j,IRUx13f  
8. 在Matlab计算照度平均值 n<?U6~F&~  
9. 返回数据到FRED中 ]5%0EE64
