    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。 U)I `:J+A  
    K9qEi{[  
    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: x 1xj\O  
    enableservice('AutomationServer', true) 3}#XA+Z  
    enableservice('AutomationServer') @;n$caw  
    :2UC{_  
    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 (P>eWw\0

    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: >eG&gc@$1$  
    1. 在FRED脚本编辑界面找到参考. `j!2uRFe>  
    2. 找到Matlab Automation Server Type Library yL3<X w|  
    3. 将名字改为MLAPP HT,kx

    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。 W6xjqNU

    现在将脚本代码公布如下,此脚本执行如下几个步骤: (8-lDoW  
    1. 创建Matlab服务器。 "O*W]e  
    2. 移动探测面对于前一聚焦面的位置。 ~~:8Yv[(  
    3. 在探测面追迹光线 ;Y|~!%2~  
    4. 在探测面计算照度 |Q)w3\S$  
    5. 使用PutWorkspaceData发送照度数据到Matlab PSQ:'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7" STS7_  
    7. 用Matlab画出照度数据 FvNSu"O~K1  
    8. 在Matlab计算照度平均值 R5;eR(24G  
    9. 返回数据到FRED中 JTh =JHJ
