    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。 yfV{2[8ux  
    thOCzGJ$  
    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: 3>;U||O  
    enableservice('AutomationServer', true) \4V'NTjB  
    enableservice('AutomationServer') 9t=erhUr  
    p_qH7W  
    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 f}*Xz.[bCp  
    D4@=+  
    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: `W"-jz5#=  
    1. 在FRED脚本编辑界面找到参考. B3K%V|;z )  
    2. 找到Matlab Automation Server Type Library |%$d/<<PZ  
    3. 将名字改为MLAPP |ek*wo  
    {`-EX  
    /+'@}u |  
    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。 "|f;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T `N(=T^*  
    1. 创建Matlab服务器。 yp8 .\.  
    2. 移动探测面对于前一聚焦面的位置。 ao 32n  
    3. 在探测面追迹光线 vh T9#) HI  
    4. 在探测面计算照度 rsrv1A=t?  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5o&L|7]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 U; ev3  
    7. 用Matlab画出照度数据 ZWYwVAo  
    8. 在Matlab计算照度平均值 wjpkh~ qo  
    9. 返回数据到FRED中 Il!iqDHz3
