FRED案例-FRED如何调用Matlab

4p;`C  
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。 vr6w^&[c^  
16(QR-  
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: >@_^fw)  
enableservice('AutomationServer', true) HBXOjr<,{  
    enableservice('AutomationServer') s*]}QmRpr  
 >Abdd  
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。 ~HsJUro

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: #h ]g?*}OJ  
1. 在FRED脚本编辑界面找到参考. SO'vp z{  
2. 找到Matlab Automation Server Type Library O m2d .7S  
    3. 将名字改为MLAPP /7F:T[  
     vXZOy%$o  
     0~/_|?]`7  
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。 N S[l/0F&

现在将脚本代码公布如下,此脚本执行如下几个步骤: r[iflBP  
1. 创建Matlab服务器。 h3 }OX{k  
2. 移动探测面对于前一聚焦面的位置。 MAPGJ"?  
3. 在探测面追迹光线 4!no~ $b  
4. 在探测面计算照度 ?IT*: A] E  
5. 使用PutWorkspaceData发送照度数据到Matlab JL{VD /f  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -x`@6  
7. 用Matlab画出照度数据 +',S]Edx  
8. 在Matlab计算照度平均值 u\;C;I-? '  
9. 返回数据到FRED中 +a{1)nCXe
