    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。 6]^~yby P  
    /)-OK7x  
    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: wR%F>[ 6.{  
    enableservice('AutomationServer', true) DfsPg':z  
    enableservice('AutomationServer') ?nCo?A  
    v(`9+*  
    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 ng6".u9

    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: !K%8tr4   
    1. 在FRED脚本编辑界面找到参考. xW. ~Jt  
    2. 找到Matlab Automation Server Type Library xCYK"v6\  
    3. 将名字改为MLAPP np6R\Q!&

    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。 gtwUY$

    1. 创建Matlab服务器。 Gpf9uj%  
    2. 移动探测面对于前一聚焦面的位置。 *Tum(wWZ  
    3. 在探测面追迹光线 AeR*79x  
    4. 在探测面计算照度 o FS2*u  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2/>u8j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *w`_(X f  
    7. 用Matlab画出照度数据 Z'!i"Jzq|{  
    8. 在Matlab计算照度平均值 hQ@E2Xsv
