    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。 %mq]M  
    z XvWo6  
    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: "<&F=gV  
    enableservice('AutomationServer', true) Qj=l OhM  
    enableservice('AutomationServer') &3JbAJ|;X  
    $nVTN.k  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Wb|IWn H$  
    p$ko=fo-*_  
    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: _zOzHc?Q  
    1. 在FRED脚本编辑界面找到参考. D( _a Xy  
    2. 找到Matlab Automation Server Type Library -ZuzJAA  
    3. 将名字改为MLAPP $0 l i"+  
    DB*IVg  
    $HH(8NoL  
    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。 &o8\ $A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1|gEY;Ru  
    1. 创建Matlab服务器。 fEpY3od  
    2. 移动探测面对于前一聚焦面的位置。 hA"N&v~  
    3. 在探测面追迹光线 ('gjf l  
    4. 在探测面计算照度 %xg"e O2x  
    5. 使用PutWorkspaceData发送照度数据到Matlab <1@_MY o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :l6sESr  
    7. 用Matlab画出照度数据 u'N'<(\k  
    8. 在Matlab计算照度平均值 2D-*Z=5^  
    9. 返回数据到FRED中 'rg$%M*(
