[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。 5HqvSfq>?

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： \)'5V!B|s  
enableservice('AutomationServer', true) bK69Rb@\A  
enableservice('AutomationServer') e\7AtlW"  
m*f"Y"B.1I  
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。 s'4%ZE2Dr

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： b2 5.CGF  
1. 在FRED脚本编辑界面找到参考. RoLN#  
2. 找到Matlab Automation Server Type Library h

3. 将名字改为MLAPP L4t(Y7  
xMr=tU1C  
%5yP^BL0  
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。

现在将脚本代码公布如下，此脚本执行如下几个步骤： ]]^r)&pox  
1. 创建Matlab服务器。 $No^\.mV  
2. 移动探测面对于前一聚焦面的位置。 mTU[khEmL=  
3. 在探测面追迹光线 \`oP\|Z  
4. 在探测面计算照度 \TS.9 >\  
5. 使用PutWorkspaceData发送照度数据到Matlab 3\2^LILLO  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Y~Z&h?H'}  
7. 用Matlab画出照度数据 Min{&?a  
8. 在Matlab计算照度平均值 'Y22HVUX  
9. 返回数据到FRED中 'TO/i:{\
