[推荐]FRED案例-FRED如何调用Matlab [复制链接]

F phDF  
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。 dfj\RIV8  
;&;W
T  
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： 76fIC  
enableservice('AutomationServer', true) 6vzk\n  
    enableservice('AutomationServer') /uqu32;o  
]
rBM5~  
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。 ><?BqRm+

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： >um

1. 在FRED脚本编辑界面找到参考. D$eB ,~  
2. 找到Matlab Automation Server Type Library F1azZ(  
    3. 将名字改为MLAPP <&!]K?Q9i

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。 4g _"ku

现在将脚本代码公布如下，此脚本执行如下几个步骤： do/)~9[4\  
1. 创建Matlab服务器。 d4^`}6@  
2. 移动探测面对于前一聚焦面的位置。 V1=*z  
3. 在探测面追迹光线 ztM<J+  
4. 在探测面计算照度 nY?  
5. 使用PutWorkspaceData发送照度数据到Matlab Bd0eC#UGkQ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v[k5.\No  
7. 用Matlab画出照度数据 6iezLG5  
8. 在Matlab计算照度平均值 Bn wzcl  
9. 返回数据到FRED中 h+7>#*DH
