    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。 W:D'k^u  
    P \<dy?nZ  
    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: <cu? g  
    enableservice('AutomationServer', true) ^.bYLF  
    enableservice('AutomationServer') "#bL/b'{  
    C"l_78  
    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 hz#S b~g  
    @y:mj \J9  
    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: 6&/H XqP  
    1. 在FRED脚本编辑界面找到参考. BDoL)}bRE  
    2. 找到Matlab Automation Server Type Library |O0=Q,<m  
    3. 将名字改为MLAPP xbJ@z {  
    SN2X{Q|*  
    :M" NB+T  
    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。 {Ic~}>w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: +g36,!q  
    1. 创建Matlab服务器。 `:WVp~fn  
    2. 移动探测面对于前一聚焦面的位置。 APxy %0Q  
    3. 在探测面追迹光线 hKq <e%oVH  
    4. 在探测面计算照度 q~*3Bk~  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9y=$ |"<(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Mazjn?f  
    7. 用Matlab画出照度数据  V[D[MZ  
    8. 在Matlab计算照度平均值 ZUGuV@&-T  
    9. 返回数据到FRED中 + $i-"^
