    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#3}kOb%  
    ud`!X#e~  
    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: rf\A[)<:  
    enableservice('AutomationServer', true) r5wy]z^  
    enableservice('AutomationServer') IUZ@n0/T  
    {vf4l4J(  
    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 azKiXr#_(  
    a}p}G\b|  
    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: L `6 R  
    1. 在FRED脚本编辑界面找到参考. aMq|xHZ  
    2. 找到Matlab Automation Server Type Library "54t7  
    3. 将名字改为MLAPP k. @OFkX.

    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。 z]d2 rzV(_

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @o/126(k  
    1. 创建Matlab服务器。 4n5r<?rY  
    2. 移动探测面对于前一聚焦面的位置。 > 3SZD  
    3. 在探测面追迹光线 r0'6\MS13  
    4. 在探测面计算照度 `{v!|.d<  
    5. 使用PutWorkspaceData发送照度数据到Matlab H4Lvw8G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Jv[c?6He  
    7. 用Matlab画出照度数据 ;jZf VRl  
    8. 在Matlab计算照度平均值 T=~D>2C  
    9. 返回数据到FRED中 K.P1|
