    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。 +uF!.!}  
    H=vrF-#  
    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: GHHErXT\a  
    enableservice('AutomationServer', true) e75 k-  
    enableservice('AutomationServer') o7feH 6Sh  
    v+Vpak9|  
    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 (/&IBd-  
    >G2o  
    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: G"jKYW  
    1. 在FRED脚本编辑界面找到参考. ^4LkKYMS  
    2. 找到Matlab Automation Server Type Library _nR8L`l*z  
    3. 将名字改为MLAPP H_'i.t 'SS  
    ~U:{~z  
    :&= TE2  
    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。 d7A08l{

    1. 创建Matlab服务器。 XD`QU m  
    2. 移动探测面对于前一聚焦面的位置。 0lNVQxG  
    3. 在探测面追迹光线 U,C L*qTF  
    4. 在探测面计算照度 ?)#dP8n  
    5. 使用PutWorkspaceData发送照度数据到Matlab P>=~\v nN#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [L1pDICoy  
    7. 用Matlab画出照度数据 9?r|Y@xh]  
    8. 在Matlab计算照度平均值 w,NK]<dU@  
    9. 返回数据到FRED中 wTFM:N
