FRED案例-FRED如何调用Matlab

ESdjDg$[u  
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。 4L'dV  
qcYF&  
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: laVqI|0q  
enableservice('AutomationServer', true) *_Y{wNF *  
    enableservice('AutomationServer') gJYB)LjH"  
>l|ao&z>bm  
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。 sdkKvo. y0

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: O>P792)  
1. 在FRED脚本编辑界面找到参考. Gn}G$uk61  
2. 找到Matlab Automation Server Type Library KW^#DI6tr  
    3. 将名字改为MLAPP pwq a/Yi  
     Hggp*(AQK  
     ')ZM# :G  
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。 ]w2nVC 3

现在将脚本代码公布如下,此脚本执行如下几个步骤: ANuIPF4NxP  
1. 创建Matlab服务器。 E+>$@STv#  
2. 移动探测面对于前一聚焦面的位置。 K5; /  
3. 在探测面追迹光线 ~zEBJgeyh  
4. 在探测面计算照度 QFn .<@  
5. 使用PutWorkspaceData发送照度数据到Matlab \>}G|yL  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &O0@)jIV  
7. 用Matlab画出照度数据 zT;F4_p3G-  
8. 在Matlab计算照度平均值 .nXOv]  
9. 返回数据到FRED中 9 U6cM-p?
