FRED案例-FRED如何调用Matlab

W/\VpD) ?;  
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。 O >+=cg  
.xwskzJ3  
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: awo'#Y2>  
enableservice('AutomationServer', true) AB\Ya4O"9  
    enableservice('AutomationServer') "[P3b"=gW  
smfI+Z S"  
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。 $%cHplQz5  
<$s sU{5  
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: w!H(zjv&(  
1. 在FRED脚本编辑界面找到参考. B(1-u!pz  
2. 找到Matlab Automation Server Type Library XQn1B3k+  
    3. 将名字改为MLAPP e(/F:ZEh

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。 g/f6N z

现在将脚本代码公布如下,此脚本执行如下几个步骤: X-nC2[tu'W  
1. 创建Matlab服务器。 6 /YJA*  
2. 移动探测面对于前一聚焦面的位置。 kd!?N  
3. 在探测面追迹光线 W9w*=W )Z  
4. 在探测面计算照度 xE@/8h  
5. 使用PutWorkspaceData发送照度数据到Matlab hZHM5J~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6Ot~Q  
7. 用Matlab画出照度数据 N8pL2y:R[P  
8. 在Matlab计算照度平均值 04dz ?`HuB  
9. 返回数据到FRED中 -O\i^?lD;
