    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。 hW$B;  
    v}!eJzeH  
    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: &*B=5W;6^u  
    enableservice('AutomationServer', true) INOw0E[  
    enableservice('AutomationServer') X(U CN0#  
    Fd":\7p  
    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 8rAOs\ys  
    cH?j@-pY  
    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: I$9^i#O'3  
    1. 在FRED脚本编辑界面找到参考. _nOJ.G  
    2. 找到Matlab Automation Server Type Library s9>f5u?dK  
    3. 将名字改为MLAPP rn#FmM

    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。 CvKXVhf0$J

    现在将脚本代码公布如下,此脚本执行如下几个步骤: LFvKF.  
    1. 创建Matlab服务器。 >j5) MF{"  
    2. 移动探测面对于前一聚焦面的位置。 l5F>v!NA  
    3. 在探测面追迹光线 :p0|4g  
    4. 在探测面计算照度 zV_U/]y  
    5. 使用PutWorkspaceData发送照度数据到Matlab T&c0j(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {L5!_] 6  
    7. 用Matlab画出照度数据 s!esk%h{K  
    8. 在Matlab计算照度平均值 ^AkVmsv;;  
    9. 返回数据到FRED中 `mXbF
