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。 }Xi#x*-D  
*h:EE6|  
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: qo- F9u1J  
enableservice('AutomationServer', true) y UAn~!s  
enableservice('AutomationServer') }>~>5jc/Pg  
wPJRp]FA  
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。 O + & xb  
AsLjU#jn  
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: c/Yi0Rl)  
1. 在FRED脚本编辑界面找到参考. oB R(7U ~0  
2. 找到Matlab Automation Server Type Library BkxhF  
3. 将名字改为MLAPP DS}rFU  
u^zitW!X$  
X,+}syK  
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。 dm=F:\C

现在将脚本代码公布如下,此脚本执行如下几个步骤: iv+jv2ZF%  
1. 创建Matlab服务器。 B8AzN9v&"N  
2. 移动探测面对于前一聚焦面的位置。 |QOJ9~hxD  
3. 在探测面追迹光线 @) ZO$h  
4. 在探测面计算照度 [Cqqjv;_  
5. 使用PutWorkspaceData发送照度数据到Matlab -wQ^oOJ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Au} ;z6k  
7. 用Matlab画出照度数据 *X l<aNNx  
8. 在Matlab计算照度平均值 p <=%  
9. 返回数据到FRED中 _G[I2]
