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。 1 <wolTf  
R-\"^BV#Z  
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: 2*0n#" L  
enableservice('AutomationServer', true) .u;'eVH)a}  
enableservice('AutomationServer') 6`)Ss5jzk  
}Q{4G  
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。 \3cg\Q+~

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: Z DnAzAR  
1. 在FRED脚本编辑界面找到参考. -V}ZbXJD  
2. 找到Matlab Automation Server Type Library 4,ewp coC%  
3. 将名字改为MLAPP p;{w0uld"

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。 `wNJ*`

现在将脚本代码公布如下,此脚本执行如下几个步骤: v0 |"[qGb  
1. 创建Matlab服务器。 E=~Ahkg  
2. 移动探测面对于前一聚焦面的位置。 Td![Id  
3. 在探测面追迹光线 zuBfkW95+  
4. 在探测面计算照度 $ dHD  
5. 使用PutWorkspaceData发送照度数据到Matlab }/Y)^  
6. 使用PutFullMatrix发送标量场数据到Matlab中 'a enh j  
7. 用Matlab画出照度数据 Py#iC#g~  
8. 在Matlab计算照度平均值 X[o"9O|<  
9. 返回数据到FRED中 7:&a,nU
