FRED案例-FRED如何调用Matlab

gG.+3=  
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。 3"my!}03  
FxK!h.C.  
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: ' i5}`\  
enableservice('AutomationServer', true) 7 u Q +]d  
    enableservice('AutomationServer') C{t}q*fG 5  
izl-GitP  
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。 y,jpd#Y

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: 1\/vS$bi(  
1. 在FRED脚本编辑界面找到参考. `\ IaeMvo  
2. 找到Matlab Automation Server Type Library .) %, R  
    3. 将名字改为MLAPP G#NbLj`h  
     ';.y`{/  
     lF46W  
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。 qJl DQc-

现在将脚本代码公布如下,此脚本执行如下几个步骤: \f Kn} ]kG  
1. 创建Matlab服务器。 wpQp1){%Q  
2. 移动探测面对于前一聚焦面的位置。 b 5K"lPr  
3. 在探测面追迹光线 fh1-]$z`~  
4. 在探测面计算照度 g.;2N9  
5. 使用PutWorkspaceData发送照度数据到Matlab ##mBOdx  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B2_fCSlg  
7. 用Matlab画出照度数据 , .=7{y~  
8. 在Matlab计算照度平均值 gth_Sz5!#  
9. 返回数据到FRED中 t(.vX
