    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。 M3`A&*\;  
    :!h H`l}p  
    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: ^k##a-t<_>  
    enableservice('AutomationServer', true) ZfikNQU9r  
    enableservice('AutomationServer') ^SCWT\E  
    VNXVuM )c  
    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 rM |RGe  
    $c47cJO)W  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: XS/TYdXB8  
    1. 在FRED脚本编辑界面找到参考. B[V=l<J  
    2. 找到Matlab Automation Server Type Library KL`>mJo$  
    3. 将名字改为MLAPP D*,H%xA  
    'YZs6rcJ  
    0yNlf-O  
    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。 $g;xw?~#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: TD7ONa-,  
    1. 创建Matlab服务器。 &r%3)Z8Et  
    2. 移动探测面对于前一聚焦面的位置。 DBDfB b  
    3. 在探测面追迹光线 gs >cx]>  
    4. 在探测面计算照度 ic#drpl,  
    5. 使用PutWorkspaceData发送照度数据到Matlab mo$*KNW%\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 zY-m]7Yf  
    7. 用Matlab画出照度数据 DUr1s]+P  
    8. 在Matlab计算照度平均值 %}:J 9vra  
    9. 返回数据到FRED中 ")OLmkC
