    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。 z"4]5&3A  
    +#@"*yj3  
    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: bZ _mYyBh  
    enableservice('AutomationServer', true) =tTqN+4  
    enableservice('AutomationServer') W" "*ASi  
    S&C1TC  
    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 9ch#}/7B

    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: ivgpS5 M`Y  
    1. 在FRED脚本编辑界面找到参考. k#TYKft  
    2. 找到Matlab Automation Server Type Library *="8?Z  
    3. 将名字改为MLAPP bSwWszd~

    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。 q}uHFp/J

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \b'x t  
    1. 创建Matlab服务器。 u.pxz8  
    2. 移动探测面对于前一聚焦面的位置。 ,''cNV  
    3. 在探测面追迹光线 >C WKH~  
    4. 在探测面计算照度 E{xVc;t  
    5. 使用PutWorkspaceData发送照度数据到Matlab =bh*[ , -  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;Lw{XqT  
    7. 用Matlab画出照度数据 (fD ;g9  
    8. 在Matlab计算照度平均值 Thy=yz;p  
    9. 返回数据到FRED中 ,[p T4G
