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。 6>gm!6`  
~wQ M ?h  
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: 1T}jK^"  
enableservice('AutomationServer', true) Z.b?Jzj  
enableservice('AutomationServer') CI1K:K AM  
jbe_r<{  
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。 +GEdVB  
&S39SV  
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: /5X_gjOL,  
1. 在FRED脚本编辑界面找到参考. >VppM  `  
2. 找到Matlab Automation Server Type Library aMJJ|iiU  
3. 将名字改为MLAPP E(_lm&,4+  
Tm2+/qO,  
uT>"(wnJ|  
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。 D `av9I

现在将脚本代码公布如下,此脚本执行如下几个步骤: v0(_4U]/  
1. 创建Matlab服务器。 >FS}{O2c  
2. 移动探测面对于前一聚焦面的位置。  K{9  
3. 在探测面追迹光线 m^ /s}WEqp  
4. 在探测面计算照度 \A6 }=  
5. 使用PutWorkspaceData发送照度数据到Matlab !p Q*m`Xo  
6. 使用PutFullMatrix发送标量场数据到Matlab中 n}C0gt-  
7. 用Matlab画出照度数据 %@8#+#@J0  
8. 在Matlab计算照度平均值 y!T8(  
9. 返回数据到FRED中 JkQ\r$ Y.
