[推荐]FRED案例-FRED如何调用Matlab [复制链接]

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。 $;Iz7:#jN  
?E|=eO"I1  
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： Y&U-d{"  
enableservice('AutomationServer', true) 5dN>Xjpu  
    enableservice('AutomationServer') l5&5VC)  
=N{?ll6x7g  
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。 @fp@1n

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： RLF6Bc  
1. 在FRED脚本编辑界面找到参考. jl(D;JnF  
2. 找到Matlab Automation Server Type Library h-;> v.  
    3. 将名字改为MLAPP ^L)3O|6c

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。 L[Z^4l_!

现在将脚本代码公布如下，此脚本执行如下几个步骤： F+Qnf'at1  
1. 创建Matlab服务器。 hZL!%sL7  
2. 移动探测面对于前一聚焦面的位置。 K{/i2^4  
3. 在探测面追迹光线 -Pt E+R[A  
4. 在探测面计算照度 z _\L@b  
5. 使用PutWorkspaceData发送照度数据到Matlab !-470

    6. 使用PutFullMatrix发送标量场数据到Matlab中 Xy 4k;+  
7. 用Matlab画出照度数据 )e`9U.C  
8. 在Matlab计算照度平均值 xZ;eV76  
9. 返回数据到FRED中 0=6mb]VUi=
