    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。 w=: c7Y+  
    qh&q <M  
    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: }_}    
    enableservice('AutomationServer', true) 1?3+>  
    enableservice('AutomationServer') wZ69W$,p  
    o|c&$)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 .IVKgQ 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: !'IZr{Y>  
    1. 在FRED脚本编辑界面找到参考. Uovna:"  
    2. 找到Matlab Automation Server Type Library b'` XFB#V  
    3. 将名字改为MLAPP y4aT-^C'

    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。 JUXBMYFus

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rj4Mq:pJ  
    1. 创建Matlab服务器。 dM19;R@4  
    2. 移动探测面对于前一聚焦面的位置。 f)gV2f0t  
    3. 在探测面追迹光线 mA_EvzXk\  
    4. 在探测面计算照度 < <Y]P+uU  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;=E}PbZt2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 RBg2iG$ 8|  
    7. 用Matlab画出照度数据 * CAz_s<  
    8. 在Matlab计算照度平均值 C8YStT
