[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。 ]c4?-Vq%u  
e0Zwhz,  
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： dI};l  
enableservice('AutomationServer', true) 0Z$=2c?xT  
enableservice('AutomationServer') %ukFn &-2@  
>)\x\e  
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。 ya.!zGH

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： 0]p! Bscaf  
1. 在FRED脚本编辑界面找到参考. _~]~ssn,1  
2. 找到Matlab Automation Server Type Library ?NkweT(  
3. 将名字改为MLAPP e=e^;K4

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。 Z<jio

现在将脚本代码公布如下，此脚本执行如下几个步骤： mCah{~  
1. 创建Matlab服务器。 >

2. 移动探测面对于前一聚焦面的位置。 2^RWGCEv  
3. 在探测面追迹光线 Vz_ac vfk^  
4. 在探测面计算照度 4I

5. 使用PutWorkspaceData发送照度数据到Matlab `<_A#@  
6. 使用PutFullMatrix发送标量场数据到Matlab中 J'{69<`Dl
