[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。 )Cu2xRr^`  
'uC=xG.*}  
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： R_W6}  
enableservice('AutomationServer', true) /|0xOiib  
enableservice('AutomationServer') mqtX7rej  
D*&#}c,*  
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。 ]sTbEw.[

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： `^ZhxFX  
1. 在FRED脚本编辑界面找到参考. "%}24t%  
2. 找到Matlab Automation Server Type Library (/7b8)g  
3. 将名字改为MLAPP j*\oK@  
xv"v='  
j(A>M_f;  
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。 YdDP;, DA

现在将脚本代码公布如下，此脚本执行如下几个步骤： E

1. 创建Matlab服务器。 !>\&*h-Cm#  
2. 移动探测面对于前一聚焦面的位置。 Q.?(h! )9  
3. 在探测面追迹光线 J#W*,%8O  
4. 在探测面计算照度 !
RP0W  
5. 使用PutWorkspaceData发送照度数据到Matlab >?O?U=:<  
6. 使用PutFullMatrix发送标量场数据到Matlab中 !YPwql(  
7. 用Matlab画出照度数据 H#i,Ve'  
8. 在Matlab计算照度平均值 Z`_x|cU?J  
9. 返回数据到FRED中 <Drm#2x!E
