    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。 LW*v/`@  
    N~+ e\K6  
    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: R>R8LIZZc  
    enableservice('AutomationServer', true) rLp (}^  
    enableservice('AutomationServer') ##BfI`FJ  
    i^hEL2S/A  
    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 y8$I=  
    L'r gCOJ<  
    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: V~fPp"F  
    1. 在FRED脚本编辑界面找到参考. wAF<_NG#  
    2. 找到Matlab Automation Server Type Library T[ltOQw?Y  
    3. 将名字改为MLAPP uc]`^,`2/

    [(m+Ejzi%  
    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。 ?XB[awTD~

     giORc  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: M6XpauR-  
    1. 创建Matlab服务器。 !dGSZ|YZ  
    2. 移动探测面对于前一聚焦面的位置。 '?uwUBi  
    3. 在探测面追迹光线 ^!rAT1(/_  
    4. 在探测面计算照度 3NSX(gC%  
    5. 使用PutWorkspaceData发送照度数据到Matlab #H.DnW  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Y>Fh<"A|$  
    7. 用Matlab画出照度数据 0F9p'_C  
    8. 在Matlab计算照度平均值 U5yBU9\G  
    9. 返回数据到FRED中 E-Y4TBZ*
