FRED案例-FRED如何调用Matlab

Cv=0&S.  
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。 m8f_w  
GS^4t mc  
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:  ~.Gk:M  
enableservice('AutomationServer', true) P"#^i<ut@T  
    enableservice('AutomationServer') >pYgF =J  
a&<<X:$Hy  
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。 `<Ftn  
NdZ: 7  
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: &vn9l#\(  
1. 在FRED脚本编辑界面找到参考. = G_6D  
2. 找到Matlab Automation Server Type Library AuCVpDH  
    3. 将名字改为MLAPP ["7}u^z@<+  
     8L@di  Y  
     *5NffiA}-  
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。 'F~u \m=E

现在将脚本代码公布如下,此脚本执行如下几个步骤: $OO[C={v[  
1. 创建Matlab服务器。 nk{1z\D{  
2. 移动探测面对于前一聚焦面的位置。 BCj&z{5"7e  
3. 在探测面追迹光线 (1o^Dn3  
4. 在探测面计算照度 ;Cy@TzO/|  
5. 使用PutWorkspaceData发送照度数据到Matlab )>/c/ B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v3NaX.  
7. 用Matlab画出照度数据 C+mU_g>  
8. 在Matlab计算照度平均值 e'`oisJU?q  
9. 返回数据到FRED中 tX_eN
