    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。 qifX7AXHr  
    CYs:P8^  
    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: ] S]F&B M|  
    enableservice('AutomationServer', true) g)2}`}  
    enableservice('AutomationServer') |WlWZ8]  
    nIKh<ws4z  
    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 fnwtD *``  
    BEN=/ v  
    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: BPe5c :z  
    1. 在FRED脚本编辑界面找到参考. tec CU[O  
    2. 找到Matlab Automation Server Type Library *N<~"D  
    3. 将名字改为MLAPP !{"{(h)+@

    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。 kC0F@'D

    2. 移动探测面对于前一聚焦面的位置。 > QDmSy*&  
    3. 在探测面追迹光线 Hh4$Qr;R  
    4. 在探测面计算照度 X^eTf-*T  
    5. 使用PutWorkspaceData发送照度数据到Matlab k*[["u^u]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b_:]Y<{> f  
    7. 用Matlab画出照度数据 @|idlIey
