[推荐]FRED案例-FRED如何调用Matlab [复制链接]

aFh'KPhe  
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。 V_|

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： 5D3&6DCH  
enableservice('AutomationServer', true) \D#+0  
    enableservice('AutomationServer') yC!>7@m  
2{g&9  
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。 8. %g&%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： EvA8<o  
1. 在FRED脚本编辑界面找到参考. NxF

2. 找到Matlab Automation Server Type Library *;lb<uLv  
    3. 将名字改为MLAPP A!$sOp

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。 u=(.}

1. 创建Matlab服务器。 [[}ukG4  
2. 移动探测面对于前一聚焦面的位置。

3. 在探测面追迹光线 c-Qa0Q  
4. 在探测面计算照度 Ow-;WO_HQ  
5. 使用PutWorkspaceData发送照度数据到Matlab V:AA{

    6. 使用PutFullMatrix发送标量场数据到Matlab中 mxwG~a'_  
7. 用Matlab画出照度数据 oL9ELtb]s  
8. 在Matlab计算照度平均值 S7R*R}
 
9. 返回数据到FRED中 Yg1HvSw\
