[推荐]FRED案例-FRED如何调用Matlab [复制链接]

$MJm*6h  
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。 mc4i@<_
?  
rx}r~0i  
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： tJN<PCG6"  
enableservice('AutomationServer', true) .9.2Be  
    enableservice('AutomationServer')  W%\C_  
av~5l4YL  
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。 5xL~`-IA&v

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： f

1. 在FRED脚本编辑界面找到参考. K$d$m <  
2. 找到Matlab Automation Server Type Library n0is\ZK 0  
    3. 将名字改为MLAPP X]y)qV)a[c

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。 m4*@o?Ow

现在将脚本代码公布如下，此脚本执行如下几个步骤： |ZQ@fmvL/p  
1. 创建Matlab服务器。 U,LTVYrO  
2. 移动探测面对于前一聚焦面的位置。 ?Q&yEGm(  
3. 在探测面追迹光线 7x<i :x3  
4. 在探测面计算照度 P

5. 使用PutWorkspaceData发送照度数据到Matlab Ps<d('=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 n93=8;&  
7. 用Matlab画出照度数据 k?7 X3/O  
8. 在Matlab计算照度平均值 +zs4a96[  
9. 返回数据到FRED中 HJY2#lSha6
