[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。 2S%[YR>>  
_[%2QwAUj*  
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： :\hcl&W:  
enableservice('AutomationServer', true) WXq=FZ-  
enableservice('AutomationServer') }-`N^  
YkWv*l  
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。 !fX&i6

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：
P ?^h  
1. 在FRED脚本编辑界面找到参考.  9t$#!2z  
2. 找到Matlab Automation Server Type Library aMv?D(Meb  
3. 将名字改为MLAPP yV"k:_O{

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。 +lYo5\1=

现在将脚本代码公布如下，此脚本执行如下几个步骤： 3{:AG,G  
1. 创建Matlab服务器。 8-#_xsZ^;  
2. 移动探测面对于前一聚焦面的位置。 8U8%XIEJ  
3. 在探测面追迹光线 ,5*Z<[*  
4. 在探测面计算照度 ) |t;nK,  
5. 使用PutWorkspaceData发送照度数据到Matlab {beu  
6. 使用PutFullMatrix发送标量场数据到Matlab中 p]jkfsCjN  
7. 用Matlab画出照度数据 0Y>5&
