    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。 &(0);I@fc  
    2e &Zs%u  
    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: FliN@RNo  
    enableservice('AutomationServer', true) **"sru;@=  
    enableservice('AutomationServer') uIBV1Qz  
    &bb*~W-  
    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 V qf}(3K0  
    r@aFB@   
    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: @*dA<N.9  
    1. 在FRED脚本编辑界面找到参考. _35?z"0  
    2. 找到Matlab Automation Server Type Library x($1pAE  
    3. 将名字改为MLAPP xi0&"?7la

    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。 ~mU#u\r(*

    1. 创建Matlab服务器。 ;|c,  
    2. 移动探测面对于前一聚焦面的位置。 nr}H;wB  
    3. 在探测面追迹光线 4*]`s|fbu  
    4. 在探测面计算照度 LT!4pD:a  
    5. 使用PutWorkspaceData发送照度数据到Matlab 4 Q.70  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3D3K:K!FK  
    7. 用Matlab画出照度数据 SU^/qF%8  
    8. 在Matlab计算照度平均值 m-K6y7t  
    9. 返回数据到FRED中 7)YU ;
