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。 DKIH{:L7

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: Je6[q  
enableservice('AutomationServer', true) b#6S8C+@  
enableservice('AutomationServer') ]Y\$U<YjO  
z#tIa  
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。 w]wZJ/U`

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: tIuM9D{P  
1. 在FRED脚本编辑界面找到参考. hd)Jq'MCS  
2. 找到Matlab Automation Server Type Library nGF +a[Z  
3. 将名字改为MLAPP 1sqE/-v1_^

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。 ppAbG,7

现在将脚本代码公布如下,此脚本执行如下几个步骤: t1']q"  
1. 创建Matlab服务器。 7>yd  
2. 移动探测面对于前一聚焦面的位置。 A,~3oQV  
3. 在探测面追迹光线 S#/BWNz|  
4. 在探测面计算照度 mfr aw2H  
5. 使用PutWorkspaceData发送照度数据到Matlab >]h{[kU %4  
6. 使用PutFullMatrix发送标量场数据到Matlab中 X=sE1RB  
7. 用Matlab画出照度数据 ._}}@V_/  
8. 在Matlab计算照度平均值 =g#PP@X]D!  
9. 返回数据到FRED中 UsE\p9mCuV
