    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。 9YKDguG  
    X#J6Umutm  
    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: \+B?}P8N*l  
    enableservice('AutomationServer', true) Wc4vCVw  
    enableservice('AutomationServer') $$gtZ{ukQ  
    I,P!@  
    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 Rt4di^v  
    &HF]\`RNr  
    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: n<R \w''x  
    1. 在FRED脚本编辑界面找到参考. g [L  
    2. 找到Matlab Automation Server Type Library +TX/g~  
    3. 将名字改为MLAPP 3M*Y= ?pI

    <Jwo?[a  
    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。 g!^J,e=

    1. 创建Matlab服务器。 mQ,{=C=D  
    2. 移动探测面对于前一聚焦面的位置。 3+ asP&n

    4. 在探测面计算照度 W-Of[X{<  
    5. 使用PutWorkspaceData发送照度数据到Matlab B$7[8h  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B\zoJg&7(
