    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。 ' D&G~$  
    42CMRGv  
    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 Jf~IQ  
    enableservice('AutomationServer', true) u mlZ(??.  
    enableservice('AutomationServer') @(c<av?  
    2Nkn C>9(\  
    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 v$G*TR<2  
    <S$21NtM87  
    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: winJ@IYW  
    1. 在FRED脚本编辑界面找到参考. zt2-w/[Q  
    2. 找到Matlab Automation Server Type Library n ;5?^Un%  
    3. 将名字改为MLAPP RuNH (>Eb

    PAwg&._K  
    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。 :WIf$P?X

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {H; |G0tR  
    1. 创建Matlab服务器。 |u;BAb  
    2. 移动探测面对于前一聚焦面的位置。 X&s\_jQ  
    3. 在探测面追迹光线 3c^=<i %  
    4. 在探测面计算照度 3cO[t\/up  
    5. 使用PutWorkspaceData发送照度数据到Matlab W 'a~pB1I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 W lQ=CRY  
    7. 用Matlab画出照度数据 o:D BOpS  
    8. 在Matlab计算照度平均值 )75yv<L2S,
