    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。 RZ9chTX/  
    Z&Z= 24q_  
    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: &(X-b"2  
    enableservice('AutomationServer', true) y}> bJ:  
    enableservice('AutomationServer') lDtl6r/  
    &Ht5!zuW,  
    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 UNescZ

    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: &n2dL->*#  
    1. 在FRED脚本编辑界面找到参考. D]5cijO6  
    2. 找到Matlab Automation Server Type Library `< cn  
    3. 将名字改为MLAPP {# TZFB

    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。 `^CIOCK%

    1. 创建Matlab服务器。 {$qLMx';  
    2. 移动探测面对于前一聚焦面的位置。 A}(Q^|6  
    3. 在探测面追迹光线 p V`)  
    4. 在探测面计算照度 r| 0wIpi6Q  
    5. 使用PutWorkspaceData发送照度数据到Matlab J*"G*x#u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "s rRlu  
    7. 用Matlab画出照度数据 {P $sQv

    9. 返回数据到FRED中 8\_YP3
