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。 %E.S[cf%8&  
u(2BQO7  
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: /< QSe  
enableservice('AutomationServer', true) hy!6g n  
enableservice('AutomationServer') rN#\AN  
agT7=hX].  
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。 j|(:I:]  
jyQVSQ s  
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: J3IRP/*z  
1. 在FRED脚本编辑界面找到参考. L;yEz[#xaT  
2. 找到Matlab Automation Server Type Library Xm@aYNV  
3. 将名字改为MLAPP ._,trb>o

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。 U|?,N0%Z1

现在将脚本代码公布如下,此脚本执行如下几个步骤: {:)vwUe{  
1. 创建Matlab服务器。 WK4@:k m6)  
2. 移动探测面对于前一聚焦面的位置。 ls @5^g  
3. 在探测面追迹光线 fnOIv#  
4. 在探测面计算照度 (}"S) #C  
5. 使用PutWorkspaceData发送照度数据到Matlab +'%\Pr(  
6. 使用PutFullMatrix发送标量场数据到Matlab中 W>$BF[x!{  
7. 用Matlab画出照度数据 sOQcx\dK  
8. 在Matlab计算照度平均值 S_5?U2%D  
9. 返回数据到FRED中 '=#5(O%pp
