    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。 [9S\3&yoh  
    /5M@>A^?'  
    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: t/z]KdK P  
    enableservice('AutomationServer', true) @ @$=MSN  
    enableservice('AutomationServer') lN94 b3_W  
    ZAe>MNtW  
    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 *yp}#\rk

    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: >o #^r;  
    1. 在FRED脚本编辑界面找到参考. v w$VR PW  
    2. 找到Matlab Automation Server Type Library z#*M}RR  
    3. 将名字改为MLAPP J0xOB;rd

    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。 /C"dwh"``

    现在将脚本代码公布如下,此脚本执行如下几个步骤: X}b%gblx  
    1. 创建Matlab服务器。 3XY;g{`=q  
    2. 移动探测面对于前一聚焦面的位置。 +P,hT  
    3. 在探测面追迹光线 `btw*{.[  
    4. 在探测面计算照度 ~6!{\un   
    5. 使用PutWorkspaceData发送照度数据到Matlab g+BW~e)  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 l]R O'  
    7. 用Matlab画出照度数据 prE~GO7Z  
    8. 在Matlab计算照度平均值 FNlzpCT~L  
    9. 返回数据到FRED中 'J~{8w,.
