[推荐]FRED案例-FRED如何调用Matlab [复制链接]

80zpRU"  
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。 5U-SIG*  
({ O~O5k  
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： 7fI2b,~  
enableservice('AutomationServer', true) 0G31Kou  
    enableservice('AutomationServer') NbC
2N)L4  
)I#{\^  
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。 ^Q6?T(%$

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： Oa2\\I  
1. 在FRED脚本编辑界面找到参考. ZNVrja*  
2. 找到Matlab Automation Server Type Library zauDwV=  
    3. 将名字改为MLAPP MyZVx|7E

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。 TjDtNE

现在将脚本代码公布如下，此脚本执行如下几个步骤： 8>@JW]  
1. 创建Matlab服务器。 lb$_$+@Vr  
2. 移动探测面对于前一聚焦面的位置。 RL:B.Lv/W  
3. 在探测面追迹光线 )X;051Q  
4. 在探测面计算照度 N>Ih2>8t  
5. 使用PutWorkspaceData发送照度数据到Matlab &?1O D5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 06O_!"GD}  
7. 用Matlab画出照度数据 2"HTD|yy  
8. 在Matlab计算照度平均值 O wuc9  
9. 返回数据到FRED中 %3O))Ug5
