    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。 ]WG\+1x9  
    e|I5Nx2)  
    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: ll#PCgIm  
    enableservice('AutomationServer', true) Wg[`H=)Q  
    enableservice('AutomationServer') sYz:(hZS  
    _heQ|'(  
    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 D|xSO~M5  
    yVL~SH|  
    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: AXyuXB  
    1. 在FRED脚本编辑界面找到参考. bke 1 F '  
    2. 找到Matlab Automation Server Type Library e\89;)  
    3. 将名字改为MLAPP C}!|K0t?

    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。 ,MLPVDN*D

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6jn<YR E-  
    1. 创建Matlab服务器。 Y/ `fPgE  
    2. 移动探测面对于前一聚焦面的位置。 lBCM; #P  
    3. 在探测面追迹光线 qAm%h\  
    4. 在探测面计算照度 PtHT>  
    5. 使用PutWorkspaceData发送照度数据到Matlab a}wB7B;,g  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d; M&X!Y  
    7. 用Matlab画出照度数据 csC3Wm{v  
    8. 在Matlab计算照度平均值 P=h2Z,2
