    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。 BiGB<Jr  
    'J^ M`/  
    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: 7sP;+G  
    enableservice('AutomationServer', true) GC?X>AC:  
        enableservice('AutomationServer') [ZwZGAP  
    \zj _6Os  
    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 x._IP,vRx^

    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: a*LT<N  
    1. 在FRED脚本编辑界面找到参考. u] C/RDTH  
    2. 找到Matlab Automation Server Type Library fR_ jYP 1

    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。 '[#a-8-JY_

    1. 创建Matlab服务器。 gfE<XrG  
    2. 移动探测面对于前一聚焦面的位置。 2 qRX A  
    3. 在探测面追迹光线 mv@cGdxu  
    4. 在探测面计算照度 ?pgdj|"a  
    5. 使用PutWorkspaceData发送照度数据到Matlab <hi@$.u_Q^  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ( Lj{V}^  
    7. 用Matlab画出照度数据 +|.}oL^}G
