    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。 )|Ka'\xr  
    6/Z_r0^O  
    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: FJW,G20L  
    enableservice('AutomationServer', true) #210 Yp#  
    enableservice('AutomationServer') }L^PZS@Jf  
    G12o?N0p  
    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 OY!WEP$F-C

    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: "VMb1Zhf  
    1. 在FRED脚本编辑界面找到参考. 0rAuK7  
    2. 找到Matlab Automation Server Type Library >aCY  
    3. 将名字改为MLAPP LftGA7uGJ)

    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。 iU# "G" &

    1. 创建Matlab服务器。 t^~itlE{  
    2. 移动探测面对于前一聚焦面的位置。 J@ 8OU  
    3. 在探测面追迹光线 J d,9<m $  
    4. 在探测面计算照度 t\n'Kuk`
