    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。 wgDAb#Zuk  
    ^PdD-tY<  
    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: =ZHN]PP  
    enableservice('AutomationServer', true) 02 FLe*zQ  
    enableservice('AutomationServer') n4?;!p<F  
    2U%t  
    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 pg!mOyn  
    kW+>"3  
    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: ym p*:lH(  
    1. 在FRED脚本编辑界面找到参考. j %MY6"  
    2. 找到Matlab Automation Server Type Library VK9E{~0=  
    3. 将名字改为MLAPP uP7|#>1%

    gISA13  
    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。 H/f}t w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: XffHF^l9F  
    1. 创建Matlab服务器。 ?@A@;`0Y  
    2. 移动探测面对于前一聚焦面的位置。 %jUZc:06  
    3. 在探测面追迹光线 %to.'R  
    4. 在探测面计算照度 ;8F6a:\v  
    5. 使用PutWorkspaceData发送照度数据到Matlab mGz'%?zj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -vT$UP  
    7. 用Matlab画出照度数据 r& RJ'z  
    8. 在Matlab计算照度平均值 +Km xo4p  
    9. 返回数据到FRED中 *~`oA~-Q
