FRED案例-FRED如何调用Matlab

n<1*cL:8B  
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。 q2/kegAT  
iNilk!d6Q3  
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: 9CAu0N5<  
enableservice('AutomationServer', true) ;rV+eb)I  
    enableservice('AutomationServer') 7>h(M+ /  
O;|jLf_If  
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。 q2s=>J';

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: 5}a.<  
1. 在FRED脚本编辑界面找到参考. WJk3*$=  
2. 找到Matlab Automation Server Type Library /qFY $vj  
    3. 将名字改为MLAPP G @EEh.s9  
     xVRxKM5 {  
     G cB<i  
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。 /PbMt

现在将脚本代码公布如下,此脚本执行如下几个步骤: WVz2 bzj  
1. 创建Matlab服务器。 nJ$2RN  
2. 移动探测面对于前一聚焦面的位置。 .m.Ga|;  
3. 在探测面追迹光线 Yhjv[9  
4. 在探测面计算照度 p+0gE5  
5. 使用PutWorkspaceData发送照度数据到Matlab 14A(ZWwq9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 WJ^]mpH9  
7. 用Matlab画出照度数据 8l'W[6  
8. 在Matlab计算照度平均值 !tb!%8{~  
9. 返回数据到FRED中 h!Y##_&&4
