    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。 ?8X+)nU@  
    'N0/;k0ax  
    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: ; . c]0  
    enableservice('AutomationServer', true) }cE,&n  
        enableservice('AutomationServer') BS#@ehdig  
    eRa1eR gP  
    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 xXu/CGzG  
    <c{RY.1[  
    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: $vdGkz@6  
    1. 在FRED脚本编辑界面找到参考. HzT"{N9  
    2. 找到Matlab Automation Server Type Library QO)Q%K,  
        3. 将名字改为MLAPP fO.gfHI

    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。 #]|9aVrr

    1. 创建Matlab服务器。 vpUS(ztvs  
    2. 移动探测面对于前一聚焦面的位置。 cv0}_<Tyx  
    3. 在探测面追迹光线 Q<r O5 -K  
    4. 在探测面计算照度 R/iw#.Yy  
    5. 使用PutWorkspaceData发送照度数据到Matlab h?DMrYk_%#  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 oZ@_o3VG  
    7. 用Matlab画出照度数据 "@E1^  
    8. 在Matlab计算照度平均值 (CH F=g  
    9. 返回数据到FRED中 2|#3rF
