    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。 .C=I~Z  
    +pefk+  
    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: (z:DTe  
    enableservice('AutomationServer', true) dP7nR1GS  
    enableservice('AutomationServer') 43HZ)3!me  
    Ul`~d !3zH  
    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 'PBuf:9lN

    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: ?: XY3!{  
    1. 在FRED脚本编辑界面找到参考. X S&oW  
    2. 找到Matlab Automation Server Type Library w9W0j  
    3. 将名字改为MLAPP W7 .Y`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。 nz}} m^-j

    2. 移动探测面对于前一聚焦面的位置。 !i dQ-&  
    3. 在探测面追迹光线 Ug1[pONk

    5. 使用PutWorkspaceData发送照度数据到Matlab V|njgcn d  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ="<S1}.  
    7. 用Matlab画出照度数据 s&gzv=v
