    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。 *2m{i:3  
    ,G$<J0R1  
    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: UQT=URS  
    enableservice('AutomationServer', true) I<&) P#"  
    enableservice('AutomationServer') Z7MGBwP(  
    kKVNE h Tp  
    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 =^ x1: Ak  
    v?q)E%5j  
    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: ) @f6  
    1. 在FRED脚本编辑界面找到参考. -zm-|6[Wi  
    2. 找到Matlab Automation Server Type Library Ez^wK~  
    3. 将名字改为MLAPP }SW>ysw'm  
    FCt %of#

    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。 ^K'XlM`a

    1. 创建Matlab服务器。 SivJaY%  
    2. 移动探测面对于前一聚焦面的位置。 HAcC& s8  
    3. 在探测面追迹光线 MF5o\-&dN  
    4. 在探测面计算照度 c38ENf  
    5. 使用PutWorkspaceData发送照度数据到Matlab KA9v?_@{F  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 tNDv[IF  
    7. 用Matlab画出照度数据 ShU1RQk  
    8. 在Matlab计算照度平均值 x?G"58  
    9. 返回数据到FRED中 (5=B^9{R
