    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。 R=s^bYdoy  
    =s[P =dU  
    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: k0!D9tk  
    enableservice('AutomationServer', true) %~YQl N  
        enableservice('AutomationServer') S:xG:[N@  
    >?0f>I%\  
    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 xm}`6B^f

    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: XX'Rv]T  
    1. 在FRED脚本编辑界面找到参考. 0Kenyn4?  
    2. 找到Matlab Automation Server Type Library [bJAh ` I  
        3. 将名字改为MLAPP 6'vt '9

    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。 3 Ho<4_I,

    1. 创建Matlab服务器。 ^LJ?GJ$g  
    2. 移动探测面对于前一聚焦面的位置。 L~xzfO  
    3. 在探测面追迹光线 L[9]Ez$2+  
    4. 在探测面计算照度 'Z(4Wuwb  
    5. 使用PutWorkspaceData发送照度数据到Matlab gEQevy`T%c  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 7U{g'<  
    7. 用Matlab画出照度数据 sy.U] QG  
    8. 在Matlab计算照度平均值 ij~023$DTt
