    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。 ~&?{hd.  
    9gLUM$Kd  
    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: dY'mY~Tv  
    enableservice('AutomationServer', true) RXF%A5FXh  
    enableservice('AutomationServer') 609_ZW;)  
    .h;PMY+  
    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 wC~ra:/?:7

    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: apxY2oE&  
    1. 在FRED脚本编辑界面找到参考. }wh sZ  
    2. 找到Matlab Automation Server Type Library :GaK.W q  
    3. 将名字改为MLAPP 7kZ-`V|\.

    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。 M#PutrH

    3. 在探测面追迹光线 {B_pjs  
    4. 在探测面计算照度 W_ =  
    5. 使用PutWorkspaceData发送照度数据到Matlab N4wv'OrL]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xp4w9.X5(  
    7. 用Matlab画出照度数据 7K|: 7e(
