    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。 M[:},?ah0  
    P`$Y73L  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: fU^6h`t  
    enableservice('AutomationServer', true) o0 &pSCK  
    enableservice('AutomationServer') {Gi:W/jJ  
    :c/](M  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 .dw;b~p  
    sry`EkS  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: )4O* D92  
    1. 在FRED脚本编辑界面找到参考. p=jIDM'  
    2. 找到Matlab Automation Server Type Library Jc9BZ`~i  
    3. 将名字改为MLAPP e b*w$|y6"

    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。 _ry7 [/)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: U/j+\Kc~  
    1. 创建Matlab服务器。 ;)rs#T;$  
    2. 移动探测面对于前一聚焦面的位置。 F#>^S9Gml  
    3. 在探测面追迹光线 JQO%-=t  
    4. 在探测面计算照度  XKEbK\  
    5. 使用PutWorkspaceData发送照度数据到Matlab <x->.R_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 nNP{>\x;"  
    7. 用Matlab画出照度数据 4+2hj*I  
    8. 在Matlab计算照度平均值 yS"; q  
    9. 返回数据到FRED中 ^BN?iXQhN
