[分享]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。 |EN

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： +ck}l2&#  
enableservice('AutomationServer', true) ;A[Q2(w+  
enableservice('AutomationServer') |Q>IrT  
*{{89E>wC  
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。 :BTq!>s

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： zdH kG_PT  
1. 在FRED脚本编辑界面找到参考. k VQ\1!  
2. 找到Matlab Automation Server Type Library D1;QC  
3. 将名字改为MLAPP L/^I*p,

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<tm"?q0

现在将脚本代码公布如下，此脚本执行如下几个步骤： t |oR7qa{w  
1. 创建Matlab服务器。 ;*&-C9b  
2. 移动探测面对于前一聚焦面的位置。 po7qmLq  
3. 在探测面追迹光线 Q NVa?'0"Y  
4. 在探测面计算照度 Sa5G.^

5. 使用PutWorkspaceData发送照度数据到Matlab @\I#^X5lv  
6. 使用PutFullMatrix发送标量场数据到Matlab中 t0?\l)  
7. 用Matlab画出照度数据 5/z/>D;  
8. 在Matlab计算照度平均值 )

9. 返回数据到FRED中
