    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。 L!>EW0  
    FS+v YqwK  
    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: TXH9BlDn  
    enableservice('AutomationServer', true) {J[5 {]Je[  
    enableservice('AutomationServer') ~#]$YoQ&O  
    VX'cFqrK3  
    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 q8=hUD%5C  
    I\y=uC  
    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: ZC!GKW P2  
    1. 在FRED脚本编辑界面找到参考. $~G=Hcl9  
    2. 找到Matlab Automation Server Type Library  f3E%0cg  
    3. 将名字改为MLAPP 12olVTuw  
    [t{ed)J  
    Q>QES-.l  
    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。 :~PzTUz

    现在将脚本代码公布如下,此脚本执行如下几个步骤: C)H1<Br7  
    1. 创建Matlab服务器。 ", Ge:\TR=  
    2. 移动探测面对于前一聚焦面的位置。 4k6,pt"  
    3. 在探测面追迹光线 ;zpSyyp@  
    4. 在探测面计算照度 $%GW~|S\C  
    5. 使用PutWorkspaceData发送照度数据到Matlab z>&|:VGG  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '*d);{D8  
    7. 用Matlab画出照度数据 7%7 \2!0J}  
    8. 在Matlab计算照度平均值 2y;J 11\  
    9. 返回数据到FRED中 #ouE, <
