FRED案例-FRED如何调用Matlab

L!xi  
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。 Dlvz )  
#ABZ&Z  
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: :V||c5B+  
enableservice('AutomationServer', true) 3Y$GsN4ln  
    enableservice('AutomationServer') O=7CMbS3  
J|73.&B  
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。 |A(Iti{v  
es7=%!0  
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: @r1_U,0e  
1. 在FRED脚本编辑界面找到参考. R:qW;n%AF  
2. 找到Matlab Automation Server Type Library f!X[c?Xy"  
    3. 将名字改为MLAPP S_H+WfIHV'  
     m8[j #=h  
     OjA,]Gv6  
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。 V0mn4sfs

现在将脚本代码公布如下,此脚本执行如下几个步骤: X:{!n({r=  
1. 创建Matlab服务器。 F#E3q|Q"BS  
2. 移动探测面对于前一聚焦面的位置。 {' H(g[k  
3. 在探测面追迹光线 W(p_.p"  
4. 在探测面计算照度 OY({.uVdX  
5. 使用PutWorkspaceData发送照度数据到Matlab ?a]mDx>xh  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #/37V2E  
7. 用Matlab画出照度数据 H\[W/"  
8. 在Matlab计算照度平均值 qH_Dc=~la  
9. 返回数据到FRED中 \i &<s;
