    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。 O!Cu.9}  
    B;je|M!d  
    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: [mvHa;-w  
    enableservice('AutomationServer', true) l<%~w U  
    enableservice('AutomationServer') R*C+Yk)Tkt  
    " CoR?[,x  
    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 z5'nS&x  
     P;/wb /  
    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: WN1-J(x6  
    1. 在FRED脚本编辑界面找到参考. 4x=Y9w0?8  
    2. 找到Matlab Automation Server Type Library 0J</`/gH  
    3. 将名字改为MLAPP ID+k`nP

    Xe+FMbBco  
    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。 2` qXD fD`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: xhS/X3<th  
    1. 创建Matlab服务器。 |%;txD  
    2. 移动探测面对于前一聚焦面的位置。 a[l5k  
    3. 在探测面追迹光线 R?SHXJ%'  
    4. 在探测面计算照度 3<V!y&a  
    5. 使用PutWorkspaceData发送照度数据到Matlab K a|\gl;V  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 X#<Sv>c^  
    7. 用Matlab画出照度数据 ^uzVz1%mM  
    8. 在Matlab计算照度平均值 ji=po;g=E  
    9. 返回数据到FRED中 k@U`?7X
