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。 Bi)1*  
*9((b;Ju  
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: B9n$8QS  
enableservice('AutomationServer', true) ED @9,W0  
enableservice('AutomationServer')  &jf:7y  
e&E""ye  
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。 Ylll4w62N

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: %X O97  
1. 在FRED脚本编辑界面找到参考. {o4m3[C7=}  
2. 找到Matlab Automation Server Type Library ZPY#<^WOzr  
3. 将名字改为MLAPP )avli@W-3j  
DnP>ed"M!

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。 gyJ$ Jp

现在将脚本代码公布如下,此脚本执行如下几个步骤: cWP34;NNM  
1. 创建Matlab服务器。 ^N _kiSr  
2. 移动探测面对于前一聚焦面的位置。 uMtq4.  
3. 在探测面追迹光线 ksT2_Ic  
4. 在探测面计算照度 B_anO{3$4  
5. 使用PutWorkspaceData发送照度数据到Matlab $uF} GP_)  
6. 使用PutFullMatrix发送标量场数据到Matlab中 (u+3{Eb  
7. 用Matlab画出照度数据 *f=H#  
8. 在Matlab计算照度平均值 =U!M,zw4  
9. 返回数据到FRED中 ?k]^?7GN
