    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。 Q',m{;;  
    {I{3(M#"  
    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: >uTPjR[  
    enableservice('AutomationServer', true) R:A'&;S  
    enableservice('AutomationServer') {"m0)G,G  
    &]< 3 ~6n  
    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 WSLy}@`Vx

    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: Z:@6Lv?CN  
    1. 在FRED脚本编辑界面找到参考. MiJ6n[iv  
    2. 找到Matlab Automation Server Type Library WL l_'2h  
    3. 将名字改为MLAPP &~#iIk~%

    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。 %cX"#+e

    3. 在探测面追迹光线 n'K6vW3  
    4. 在探测面计算照度 ~c* UAowS  
    5. 使用PutWorkspaceData发送照度数据到Matlab Mra35  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ZenPw1-  
    7. 用Matlab画出照度数据 5M:D?9E+  
    8. 在Matlab计算照度平均值 KE.Dt  
    9. 返回数据到FRED中 "MnSJ 2
