[技术]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。 ~J2Q0Jv  
zV&3l9?U  
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： drZw#b  
enableservice('AutomationServer', true) )5t_tP
v  
enableservice('AutomationServer') L9kP8&&KK  
*=Fcu@  
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。 dg!sRm1iZ:  
|s^ar8)=)  
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： Yx%%+c?.  
1. 在FRED脚本编辑界面找到参考. f6"j-IW[z  
2. 找到Matlab Automation Server Type Library #X8[g_d
/  
3. 将名字改为MLAPP Qd./G5CC

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。 +?<jSmGW

现在将脚本代码公布如下，此脚本执行如下几个步骤： qa~[fORO[  
1. 创建Matlab服务器。 ?gtkf[0B|  
2. 移动探测面对于前一聚焦面的位置。 oN$ZZk R  
3. 在探测面追迹光线 3q>"#+R.t  
4. 在探测面计算照度 tWiV0PTI  
5. 使用PutWorkspaceData发送照度数据到Matlab H5AY6),  
6. 使用PutFullMatrix发送标量场数据到Matlab中 e>^R 8qM?  
7. 用Matlab画出照度数据 ~V&R

8. 在Matlab计算照度平均值 @CmxH(-i-  
9. 返回数据到FRED中 $!f$R`R^Q\
