[推荐]FRED案例-FRED如何调用Matlab [复制链接]

;/+U.I%z  
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。 H5UF r,t  
4)'U!jSb  
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： R)isWw4  
enableservice('AutomationServer', true) '
W("s  
    enableservice('AutomationServer') YZtd IG  
|*-<G3@  
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。 `}bvbvmA  
inK;n  
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：
*_}0vd  
1. 在FRED脚本编辑界面找到参考. #<u;.'R  
2. 找到Matlab Automation Server Type Library O;}
K7rSc  
    3. 将名字改为MLAPP HGd

     aS\$@41"  
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。 i*!2n1c[

现在将脚本代码公布如下，此脚本执行如下几个步骤： 0O*kC43E_  
1. 创建Matlab服务器。 @A*>lUo  
2. 移动探测面对于前一聚焦面的位置。 QH,(iX6RY  
3. 在探测面追迹光线 `QW=<Le?  
4. 在探测面计算照度 P4/~_$e  
5. 使用PutWorkspaceData发送照度数据到Matlab %so{'rQl  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 A&WC})H5  
7. 用Matlab画出照度数据 E7aG&K  
8. 在Matlab计算照度平均值 =1,1}OucP  
9. 返回数据到FRED中 Sw5-^2x0'
