    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。 \@ N[  
    --7@rxv  
    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: j 4(f1  
    enableservice('AutomationServer', true) M^/ZpKeT"  
    enableservice('AutomationServer')  ~>3#c#[  
    2(9~G|C.  
    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 _+0c<'  
    -x>2Wb~%  
    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?."cuTt  
    1. 在FRED脚本编辑界面找到参考. "3Ckc"G@  
    2. 找到Matlab Automation Server Type Library nc#} \  
    3. 将名字改为MLAPP pEG!j ~  
    *OY Nx4k  
    xl(R|D))  
    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。 bI)%g

    现在将脚本代码公布如下,此脚本执行如下几个步骤: p,mKgL63  
    1. 创建Matlab服务器。 <x:^w'V_b  
    2. 移动探测面对于前一聚焦面的位置。 Lhxg5cd  
    3. 在探测面追迹光线 )6U^!95  
    4. 在探测面计算照度 9Om3<der  
    5. 使用PutWorkspaceData发送照度数据到Matlab M{XBmDfN  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7<93n`byM  
    7. 用Matlab画出照度数据 ZBc8 ^QZ  
    8. 在Matlab计算照度平均值 w.-J2%J   
    9. 返回数据到FRED中 TJ0;xn6o
