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。 MRmz/ZmRM  
hRA.u'M  
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: 0&EX -DbV  
enableservice('AutomationServer', true) t,MK#Ko  
enableservice('AutomationServer') 5X~ko>  
a^sR?.+3  
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。 u1nv'\*  
K$(U>D|  
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: v[lytX4)  
1. 在FRED脚本编辑界面找到参考. 8t6h^uQ  
2. 找到Matlab Automation Server Type Library nPv2: x  
3. 将名字改为MLAPP R %}k52`  
oNiS"\t  
0BE%~W  
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。 WqTW@-}ID

现在将脚本代码公布如下,此脚本执行如下几个步骤: rJNf&x%6  
1. 创建Matlab服务器。 hefV0)4K  
2. 移动探测面对于前一聚焦面的位置。 l~f +h?cF  
3. 在探测面追迹光线 vTB*J,6.  
4. 在探测面计算照度 O<%U*:B  
5. 使用PutWorkspaceData发送照度数据到Matlab e348^S&rG  
6. 使用PutFullMatrix发送标量场数据到Matlab中 [ BN2c  
7. 用Matlab画出照度数据 JWxPH5L  
8. 在Matlab计算照度平均值 4.VEE~sH$  
9. 返回数据到FRED中 <[pU rJfTr
