FRED如何调用Matlab

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。 +b.<bb6  
Y]P'; C_eP  
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: 36*"oD=@  
enableservice('AutomationServer', true) `g<@F^x5  
enableservice('AutomationServer') D*o_IrG_(  
1LZ?!Lw  
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。 VtUe$ft

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: xM8}Xo  
1. 在FRED脚本编辑界面找到参考. j5|_SQOmt  
2. 找到Matlab Automation Server Type Library $]%;u: Sa  
3. 将名字改为MLAPP HlqCL1\<  
P_B#  
Al09R,I;  
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。 ^G[xQcM73

现在将脚本代码公布如下,此脚本执行如下几个步骤: 8B JxD<  
1. 创建Matlab服务器。 wdS^`nz|  
2. 移动探测面对于前一聚焦面的位置。 U[*VNJSp  
3. 在探测面追迹光线 WW{5[;LYiB  
4. 在探测面计算照度 5B#q/d1/a  
5. 使用PutWorkspaceData发送照度数据到Matlab %I9{)'+@x  
6. 使用PutFullMatrix发送标量场数据到Matlab中 1"?KQU  
7. 用Matlab画出照度数据 g34<0%6jd  
8. 在Matlab计算照度平均值 8*!<,k="9  
9. 返回数据到FRED中 8>x!n/z)
